Review Lionsteel Q4ttro

  

-  a luxury EDC knife from Italy

A few years ago, Lionsteel released a knife named the T.R.E.—standing for "Three Rapid Exchange"—referencing its three opening methods and a clever feature that allowed both the flipper tab and the thumb stud plate to be unscrewed. It was considered so innovative that it won the "Overall Knife of the Year" award that same year.

That was back in 2015, so what could be more fitting than to mark its tenth anniversary in 2025 by releasing a model that serves as both a tribute and an upgrade—taking things a step further in every respect?

The knife was named Q4ttro. Both the name and the spelling hint at what it is all about. But more on that later.

Lionsteel Q4ttro

Just like its predecessor and the majority of knives in LionSteel’s catalog, it is designed by Molletta—whose real name is Michele Pensato*. If you are familiar with his work, it is not difficult to spot both his design elements and LionSteel’s specialties in this knife. I am thinking, for instance, of details such as rounded blade spines and the micro-pattern found on the titanium scales.

In terms of technology, the Q4ttro is also at the forefront regarding materials and, to some extent, innovations—even though it doesn't come close to the "spaceship" in LionSteel's catalog that is the ROK**.

I have previously reviewed the T.R.E.—the model this knife succeeds—although the version I own, strangely enough, lacks the very system that gave it its name.

As is typical for LionSteel products, the Q4ttro comes in several versions. This particular model is made entirely of titanium, but it is also available with a presentation-side scale made of Micarta, G10, or carbon fiber. It is worth noting that the G10 and Micarta versions feature a G10 backspacer instead of a titanium one.

Short version: Lionsteel Q4ttro, a very likeable EDC knife made of exclusive materials, although perhaps with an opening method too much.

Blade

The blade shape is not unique in any way—neither for knives in general nor for LionSteel. However, the proportions bear the unmistakable stamp of Molletta, even if the belly is slightly less pronounced than is typical for his designs. It is clearly a drop-point blade, an appearance enhanced by a small swedge that both accentuates the lines and thins out the tip, making it more effective. The blade’s most distinctive feature is, of course, the prominent nail nick—or rather, the cutout that passes all the way through the blade to form a narrow, rectangular hole. It serves two functions, a point I will return to later.

The blade is 84 mm long and 3.8 mm thick—quite substantial for a knife of this size. The blade height is 25 mm.

The blade features a transverse semi-gloss satin finish. Markings are present but well-chosen in terms of format: small and relatively discreet. The presentation side displays the Lionsteel logo, along with "Maniago" and the steel type. The text "Molletta" appears on the opposite side.

As is typical for Lionsteel knives, the spine is rounded. This also applies to the transition between the blade and the base of the flipper tab—all examples of the attention to detail at which they excel.

The steel in this knife is of the same high quality as all the other materials—or how about CPM MagnaCut?

Like the other materials used in this knife, the blade steel is of the highest quality—take CPM MagnaCut, for instance. It is one of the latest materials generating buzz among enthusiasts—or rather, the online community. It is a so-called "super steel" that truly lives up to the name, offering exceptional corrosion resistance while also being capable of taking and retaining a razor-sharp edge. But the benefits don't stop there; this powder steel is also tough—a quality that is often difficult to combine with the others. This means the edge is highly resistant to chipping, something that cannot be said for all stainless steels.

Another somewhat unique characteristic is that MagnaCut—unlike other high-performance steels such as S90V and M390—is relatively easy to sharpen. The reason lies in having less chromium, both figuratively and literally: the carbides are smaller, making maintenance easier, and the percentage content is lower. In any case, we are talking about the *crème de la crème* here—among the finest steels you can find in a folding knife.

Of course, this assumes the steel has been properly hardened and heat-treated—something LionSteel has faced criticism for in the past. However, I must admit I haven’t experienced any issues with their knives. I suspect this is because my testing simply involves using the knives—albeit intensively and far more than I would under normal circumstances. I never try to "kill" them with insane stress tests or push the materials to their limits by forcing a failure. Nor do I test the knives using my own Rockwell tester or other machinery; I leave that to the metallurgy enthusiasts.

In this case, the hardness is rated at 60.5–62.5, which should be perfectly adequate for this type of steel. I certainly haven't noticed it being soft in any way.

The Q4ttro features a sleek drop-point blade with a slightly shallower belly than some other models from Molletta.

However, geometry and grind can be more important than the choice of material, and on that point, I have to offer some criticism. Lionsteel hasn't quite dared to trust the material enough to grind it sufficiently thin behind the edge. As it stands, the Q4ttro measures around 0.7 mm. MagnaCut is definitely capable of performing well with a thinner grind. I would like to see that figure nearly halved, or at least brought down below 0.5 mm.

The Q4ttro doesn't cut poorly—the factory edge was sharp enough—but it doesn't cut quite as well as it could have. 

Overall, however, I find this blade shape and size optimal for EDC use. It offers both a straight edge and a belly to work with. The latter is important in my book, as it facilitates tasks performed against flat surfaces; for instance, you can't perform small "rocking cuts" with a completely straight edge. The size provides enough edge for most tasks I can think of, with the exception of the very heaviest ones—though for those, it might be time to switch to a fixed-blade knife anyway.

I also like the tip, which is sharp enough for the small tasks I use it for. It is thin without being too fragile.

Although the Q4ttro doesn't have the best edge geometry, the full flat grind helps the blade glide through most materials with ease—especially everyday materials like cardboard and various types of plastic. The quality of the steel is evident in the long intervals between maintenance sessions. However, while writing this review, I noticed a small nick in the edge; I plan to grind it out and, while doing so, consider whether to slightly reprofile the blade.

    

Handle

If the blade’s standout feature is its superb material, the same can be said for the handle. It is made of titanium, a material used for the handle scales, backspacer, and pocket clip alike. Additionally, the presentation side features an inlay of multicolored carbon fiber. Yet, the defining characteristic of this knife is not the material itself, but rather how it has been finished; there are both major and minor details here worth examining.

A handle made entirely of titanium, including the backspacer. The presentation side features an inlay of "marble fat carbon fiber".

Lionsteel has many integral knives in its lineup, but the Q4ttro is not one of them; instead, this version features two standard titanium handle scales. Yet, "standard" doesn't quite do them justice, as they are more extensively machined than most knives.

The most obvious feature is the handle's brown-bronze anodized finish. Additionally, the presentation side has a milled recess designed to house a decorative carbon fiber inlay. It is also evident that care has been taken to round and bevel the edges. Lionsteel has even rounded the interior of the blade channel in an exemplary fashion—a detail that is sometimes overlooked. Simply put, the entire knife is exceptionally well-made.

Everything is titanium, from the finely rounded sides with their micro-pattern to the "floating" back spacer.

The same applies to the minimalist clip mount and—not least—the fact that, despite the knife not being a heavyweight, the interior has been skeletonized to reduce weight. There is a cutout beneath the carbon fiber, and even the lock bar has been lightened. Another detail on the handle scale is the triangular pivot screw; naturally, this prevents it from spinning freely when the blade tension needs adjustment. There is also a dedicated "landing zone" for the index finger when using the flipper mechanism; rather than a sharp edge, there is a recess that allows the finger to land more softly.

There are many details to examine on the Q4ttro, such as the quality of the chamfering where the index finger lands after using the flipper tab, the clip attachment, or the triangular pivot screw.

The attention to detail doesn't stop there; it is also worth noting that all the screws are driven in from the same side. The three screws holding the knife together are of the Chicago-screw type, preventing the threads from cutting directly into the titanium. They are T6 size—except for the pivot screw, of course, which is a T8. The only screws threaded directly into the titanium are the ones securing the carbon fiber scale. That scale, incidentally, is of high quality. The only potential criticism—if one must find one—is that its edges are quite noticeable to the touch.

Surrounding the perimeter is a reinforcement resembling a metal bolster. The entire handle features an intricate pattern that adds visual interest while providing some tactile feedback—though I wouldn't go so far as to say it makes the grip more secure.

Finally, we come to the backspacer, which is also crafted from the same anodized titanium as the rest of the handle. It is also what is sometimes referred to as a "floating" backspacer; its shape does not cover the entire spine, leaving sections open.

The handle is simple, fairly straight, and well-shaped, making it suitable for any grip.

Its size is comparable to the TRE, as the handles share significant similarities. However, everything here is slightly larger—measuring 112 mm in length, 12 mm in thickness, and around 25 mm in height—so it fills the hand better than its predecessor.

This size also allows all four fingers to fit perfectly. While the handle’s construction and details are sophisticated, its shape is not; rather, it is deceptively simple—the kind of simplicity found in great design that just works. It remains fully functional regardless of the grip: whether using a standard hammer or saber grip, holding the knife edge-up, or employing a reverse grip. It handles just as well in a pinch grip as it does in a full fist. Simply put: it is well made.

Opening and Lock

Beyond its fine materials and attention to detail, this is the area where the Q4ttro is meant to shine. It boasts no fewer than four different ways to open the blade. Two—or perhaps even three—of these methods involve the nail nick or the hole in the blade, while two are linked to the dual flipper tabs. The question that immediately arises is: do they work well, or is it a case of quantity over quality?

Here lies a partial explanation for the knife's name: it can be opened in no fewer than four different ways!

First, the knife can be opened using two hands. This is done quickly by gripping the cutout, which offers a good hold for the purpose. Nothing complicated there. That same cutout also serves as a blade hole—Spyderco style. However, given how narrow it is, the functionality isn't quite on the same level; you have to hit the right spot and press your thumb down firmly against the blade itself to generate the necessary friction. Once you do that, it works reasonably well—after all, the blade runs on ball bearings. Then there is the same rule that applies to other knives with this type of lock: you absolutely must not place a finger on the lock bar. That extra pressure makes it very difficult to deploy the blade.

The same notch or cutout also allows someone with a bit of manual dexterity to use a flick of the index finger from the other side to deploy the blade. The function isn't perfect here either; the resistance is tuned to accommodate the other two opening methods. But if you get the technique right, it works well enough.

The Q4ttro also features LionSteel's "REF" system, which means the flipper tab can be removed.

Then, it’s hard to miss the two flipper tabs. One is elegant, the other ugly. One is removable, the other fixed. The standard one—or the one on the spine, depending on your preference—is equipped with a so-called REF system, which is LionSteel’s name for a detachable flipper tab. The knife generally looks much better without it, but since it offers the best way to open the blade, I put it back on. It isn’t perfect, though; it’s quite small and somewhat angular in shape. That said, it’s better than having your finger slip off. It works reasonably well for a LionSteel, though snappy openings have never been their forte.

I am not, however, a big fan of the front flipper. If you turn the knife sideways in your hand and plan your move, it works. But it is neither small nor discreet. This is likely because it has to be large—a necessity arising from the fact that the tip area is already occupied, forcing the flipper tab lower relative to the pivot screw, which affects the geometry.

So sure, there are four opening methods, and all of them work, though perhaps none stands out as the absolute best.

Den här kniven har ett välfungerande ramlås 

The lock is straightforward. It is a well-made titanium frame lock featuring all the associated attributes—namely, a replaceable steel lock-bar insert with an overtravel stop. There is little more to say other than that it works well. The blade is held securely in place with no play in any direction, and the lock bar is easily accessible for disengagement thanks to the generous cutout in the handle scale.

To Carry

The Q4ttro weighs in at 106 grams. It isn't particularly heavy, and as I mentioned earlier, the handle is 11.2 cm long—nothing to be concerned about there, either. All in all, it’s a comfortable knife to carry in your pocket. Admittedly, metal parts protrude from the front end like a miniature airplane graveyard, but none of them snag on anything. The larger one points downward into the pocket—so don't keep anything else in there—and the other is fairly low-profile, albeit a bit too angular for my taste.

As for the surface finish, it doesn't interfere with either drawing or stowing the knife; the titanium's micro-pattern has no impact on that aspect of handling.

The clip is a milled titanium clip that matches the knife's appearance well and also performs effectively.

Another positive feature is that the clip—despite being a milled titanium design—works excellently. Sometimes you encounter versions of this type of clip that are essentially just a metal hook; that is not the case here. It is an elegant clip that complements the knife’s appearance well, especially since it shares the same color and pattern as the rest of the handle.

LionSteel opted to secure it with just a single screw, but a small locating pin prevents the clip from twisting sideways.

Its functionality benefits from the decision to keep the profile slim; this ensures sufficient tension to easily slip it over the edge of a pocket—such as on a pair of jeans. It handles most fabric thicknesses well, though perhaps not much beyond that.

To Conclude

In my opinion, the Lionsteel Q4ttro is a rather particular knife. I knew somewhat what to expect, as I own other knives from them designed by Molletta, yet there were still some surprises. I anticipated a highly refined knife featuring patterned, chamfered, and ground surfaces throughout. The specifications also hinted at top-tier materials—particularly the blade steel; while MagnaCut certainly wasn't brand new to the market, it was relatively untested in this specific context when the knife was released last year.

The promotional material also gave a hint as to how the knife could be opened—something I was naturally curious about!

Q4ttro is an excellent EDC knife—shown here alongside the TRE, the knife it pays tribute to and which preceded it.

However, I do have to offer some criticism in that regard. More options don't necessarily mean better. For one thing, there is a risk that the blade resistance isn't optimal for any single opening method. For another, the knife feels "cluttered" at the front end, featuring no fewer than four different opening methods—two of which are flipper tabs. As a side note, I also find that aspect less visually appealing.

Having multiple methods can also be tricky for experienced knife users, as you might find yourself hesitating over which one to choose. That said, it is something you can get used to with practice. For a while, I used the thumb hole without the spine flipper, but since the flipper works best, I ended up putting it back on.

I cannot help but conclude that, in this case, it is likely more a matter of realizing an idea than a considered decision based on necessity. "Three" was to be celebrated—and this through both "more" (in terms of scale) and "more" (in terms of an additional opening method).

I also feel that Lionsteel hasn't fully utilized the potential of MagnaCut. My advice, once again, is to go all out and keep the edge thin. After all, this is a small—well, not *that* small—folding knife intended for EDC use, not a tool for building shelters. But there’s bound to be some crazy YouTuber who manages to snap a blade. Unfortunately, that type of review contributes to some manufacturers designing their knives accordingly.

Lionsteel Q4ttro has stayed with me right into the autumn

It is also worth noting that the Lionsteel Q4ttro features a well-crafted handle that offers great comfort. I might not go so far as to call it an ergonomic masterpiece—I reserve that distinction for another Lionsteel model, the TM1—but it is certainly very good. The blade shape also makes for a highly capable EDC knife.

The fact that it is also a handsome knife (with the possible exception of the front flipper) certainly doesn't hurt. All in all, it is a highly potent knife with plenty of details for the enthusiast to examine and appreciate. I therefore recommend it to anyone looking for a sophisticated folding knife made from top-tier materials—one that stands out from the crowd. It has that special something: personality.

The recommended price on the website is €320, with retail prices in Europe starting at that figure and going up.

Review SRM Twin

  

-  A real light heavyweight

Who doesn't love a dagger? Or at least the elegant aesthetics that come with that blade shape. It's something that SRM has taken note of in this model called Twin. A knife that is characterised by the slender symmetrical shape, which is the epitome of the knife type.

However, this is not a large fixed-blade knife, but a small knife intended for EDC use, a pure pocket knife, quite simply.

SRM 251 Twin

The SRM 251MB Twin is currently available in four versions. The blade steel is the same regardless of which one you choose, but the handle material and, therefore, the appearance differ. To choose from, there is G10 available in either a white or multi-coloured appearance, or as seen here, with a carbon fibre surface. The alternative is otherwise a brown Micarta. Depending on the chosen handle, the blade is either covered with a grey or black coating or sandblasted.

Twin, a very elegant and symmetrical knife

Short version: SRM Twin, A small, lightweight pocket knife for those who appreciate symmetry and hidden opening methods!

Blade

This entire knife is built around symmetry, and this is reflected in both the handle and the blade. Consequently, a dagger blade is found here. However, it is only sharpened on one side. But since the entire blade disappears into the handle when the knife is closed, you could theoretically double-sharpen the knife.

The length of the blade is 76 mm, and the width is at most 22 mm. But the shape means that immediately after the ricasso, it begins to taper towards the tip. Then the blade is made even lighter and possibly stronger by having a fuller that runs along the middle of the blade.

The thickness of the stock is 2.5 mm, and it tapers via a secondary edge of 9 mm to a thickness of a measly 0.2 mm behind the edge. The factory edge was also very sharp, it can be said. These two details are how to make a blade of this type a decent cutter. 

The dagger blade is single-edged with a grey surface and a fuller along the middle.

The steel used is Böhler N690. A well-known steel with properties that tend towards the middle when it comes to "budget steel". I put it in parentheses as it is certainly debatable what it is and what it means. Especially if it is contrasted with perhaps more important properties such as blade and edge geometry, hardening and heat treatment.

But it is stainless steel that is excellent for small folding knives. Here, the stainless properties have been reinforced by a surface layer of titanium. Perhaps more for appearance than anything else. 

The marking on this blade is worth a comment. There is a lot of information on the blade, but it is so cleverly hidden that it is barely distinguishable. On the presentation side, you can find SRM's logo, but in a small format and a colour scheme that makes it barely visible. Then they have hidden everything from the serial number, model designation and steel type on the other side in a size that requires a magnifying glass to read. It is found in the blade notch and on the ricasso.

The steel used is N690

Once put into use, the Twin is an excellent pocket knife. It cuts really well, and the blade is, as I said, not too thick, and the edge is sharp. Excellent for EDC use, in other words. But what is the crazy person saying, you might be wondering? A small dagger blade can't be very useful, right? In fact, it is if you use the knife for what small pocket knives have always been used for: small tasks. I wouldn't force this knife into a role it wasn't intended for. It's hardly an outdoor knife or hunting knife, so butchering moose or building a shelter outdoors is, of course, not its strength. 

On the other hand, the Twin is an excellent knife for opening things, the small, quick cuts needed to get into boxes and packaging, removing tape, cutting nylon straps, etc. Then, it is also good for precision work, especially with that tip. So if you've got some debris in your hand that needs to be removed, this is as close to a scalpel as you get.

Handle

Cigar, that's all I have to say about the handle. Or maybe not really everything. But the handle on the Twin has a typical cigar shape. Completely symmetrical, which reflects the blade with a narrower front end and a narrower back end. Both ends are also strongly rounded, which not only gives a softer impression, but also feels that way in the hand.

The handle is both aesthetically pleasing and comfortable to hold

The construction consists of two halves of steel that make up the frame itself. The side panels are recessed into them. The knife is held together by only two screws. A screw at the back of the handle and the pivot screw itself, which is adjustable. Or, well, it would be if it weren't soaked in threadlocking. I have to admit, it won. I came very close to tearing the threads when I tried.

In this version, the frame has the same grey colour as the blade. This makes me suspect that the same titanium coating was used for both, but I'm not entirely sure on that point.

The two halves of the handle are visible, which suggests an integral construction, even if it's not

This version features sides made of a G10 laminate with a carbon fibre surface. The surface is not only well polished but also elegantly curved. There is not a single flat surface on this knife. It not only looks luxurious, it feels so too. It is obvious that some effort has been put into the design. Sometimes simplicity is a virtue.

Det finns en anledning till att den här formen var vanlig på äldre knivtyper, den fungerar i alla grepp!

In fact, the Twin works great in every grip you can think of. This applies regardless of whether you prefer a more powerful hammer grip or one more intended for finesse. But the same approach when it comes to the area of ​​use returns here. Twin is a small and neat pocket knife with the limitations that this entails. If you have large hands and want something solid to hold, this is not the knife for you. Similarly, the knife lacks finger protection, so I also do not recommend that you stab with the knife.

The length of the handle is 102 mm, and the thickness is 12 mm. The advantage of a hidden flipper and this overall shape, however, is that every millimetre of the handle can be used; nothing is wasted.

Opening and Lock

SRM rightly makes a point of equipping the Twin with what they call an "invisible flipper". It's true. Unless you have the knife in your hand or read the description of it, it's hard to tell that this is a front flipper knife. One that works damn well, too.

The entire base of the blade is equipped with jimpings that provide excellent grip for a finger that is pulled over the front of the blade. You don't have to aim or pre-tension your finger, as is sometimes the case with other types of flipper tabs. Just pull your finger, and the blade flashes out.

Twin offers one of the most discreet flipper features I've encountered

In addition to good grip and geometry, the process is aided by a light blade and ceramic ball bearings. The Twin is both easy and quick to open.

And as with all knives with this type of lock, it can, of course, be used to open the knife. Simply pull the locking bolt back, and the blade will swing freely and can be flicked both in and out. The fact is that you have to consciously reduce the speed on the way in, otherwise the blade will bounce back out.

The lock called "Ambi lock" is SRM's extremely well-executed interpretation of a cross-bar lock.

SRM calls their version of the Crossbar Lock the Ambi Lock. It's a technique they've mastered from the start, and the Twin is no exception. The lock is reliable, as it always locks and holds the blade in place with authority. There's no movement in the blade that you can feel.

However, I'm not entirely thrilled with the fact that the pivot screw is so tight that if I needed to adjust the blade, it's currently impossible. 

To Carry

Sometimes I write "it doesn't get much better than this" when it comes to certain aspects of knives. That's something that definitely applies to how the Twin is to carry. The external attributes are there with a length of almost exactly one decimeter. To that should be added, however, that it is a very rounded decimeter. The ends are softly shaped, and the sides are arched.

This means that the maximum thickness of the handle is only found in the middle. At the edges, the handle is only 9 mm thick. Then it is even better with a modest weight of only 70 grams.

Furthermore, the surface of the handle is very soft and does not contribute to any friction that can irritate either a hand on the way down to the pocket or tear the fabric.

But even more notable is the absence of anything that protrudes. As you can see, there is nothing that can be in the way. Then the package is completed with a well-functioning clip.

I like this variant of a wire clip

Twin has a black wire clip that matches the appearance of the knife well. The fact that SRM chose this type gives a lighter and airier impression than a more massive clip would have made, so it is a choice I think is correct. The function of the clip is very good. The spring works, and the ramp that is there comes over most fabric edges. Especially since the material underneath does not provide any friction to speak of. This makes Twin easy to pull and put away. And since it weighs as little as it does, it is basically completely unnoticeable where it is located.

The only disadvantage is that the clip cannot be moved to the left side. But after trying to carry the knife on the left side, it can be concluded that since the model itself is completely symmetrical, you can just pull the knife, twist it in your hand and open it with your left hand as well. No major problems, therefore.

Another advantage of the clip is that it does not interfere when cutting with the knife. On the contrary, it helps when opening and closing the knife, as you can rest your fingers against it for a better grip.

To Conclude

It can be said straight away that, in my opinion, this is one of the best-looking knives SRM has put together. Twin not only has that very dagger-like appearance, but it is also very well made. All quality markers can be checked off. The blade is centred, the factory edge is sharp and symmetrical, the opening is soft and nimble and so on. But what stands out the most is probably the details in the seemingly very simple handle.

It's about things like how they chose to keep the colour scheme consistent with the frame, blade and screws. How the marking is tasteful and discreet, but not least about how they rounded and bevelled all edges. The entire knife is as soft to hold as it looks in the picture.

Twin, a slim little dagger for your pocket that is surprisingly practical

The fact that it is comfortable to grip is followed by the fact that it is pleasant to work with. The knife is well-balanced, which reinforces that it is light. The blade is surprisingly practical given the frames I mentioned earlier. As you can see, it is not a survival knife. But for all sorts of smaller tasks, it is excellent.

SRM Twin is a real jewel in your pocket

The SRM Twin is therefore a pretty good knife for those who like this type of aesthetic but who at the same time want something that, despite its sleek appearance and neat format, is quite practical.

In addition, the Twin is not expensive; currently, the recommended price on the website is $79.95, which is about the same amount in Europe, albeit in Euros.

Review QSP Jumping Jack

  

-  the result of a successful collaboration

The modern grandfather knife, or something like that, is what I called this knife when it was presented here on the blog the other day. I'm, of course, referring to this slip joint from the now very established brand QSP.

The model has been named Jumping Jack, and here I intend to give a description of it so you can decide whether it is something for you or not.

QSP Jumping Jack

Jumping Jack is a lot of things at the same time, and you have to start by deciding whether you like slip joints or not, as the knife lacks a lock in the true sense. In addition, it is a so-called "modern traditional" which means that it is not exactly the same as, say, an old Case from the fifties. The appearance is certainly found here, but the materials and manufacturing technology are modern. Specifically, this means that the construction is screwed instead of riveted, as an example.

If some of you think you recognise the design language from elsewhere, I can attest that you are right. This is a collaboration between QSP and Spencer Marquardt, who is usually involved with Finch Knives.

Jumping Jack, a really nice slip joint

Short version: QSP Jumping Jack, a "modern traditional" and an essence of what such a knife can be. The design language is classic, but the performance is modern

Blade

The blade shape is a bit special. A combination of older times and Finch Knives, because the blade is wider towards the front than towards the base. Otherwise, this is a hybrid but where everything breathes a classic Spey blade. Something that was traditionally used to castrate animals. Hence, the steep tip, you simply don't want to poke holes in the wrong place. But the history is older, and the blade shape is good for precise cuts, and therefore it was also used in fly fishing contexts. Hence the name, it is named after the river Spey in Scotland.

Jumping Jack has a 70mm long Spey blade made of 14C28N

So far, it's classic, but some details are more modern. It's about things like the finish, a nice shiny satin, but mainly about the material. Here, stainless steel is used in the form of Sandvik 14C28N. A Swedish steel that was developed together with Kershaw Knives to be a better version of 12C28N.

As a steel, it is very all-round and one of my favourites when it comes to so-called mid-range steels. It has balanced properties and can handle most things. However, it is not extreme, so it does not hold its sharpness as well as a "super steel". It is also not as shock-resistant as the best in its class. But none of those properties is necessary in a small pocket knife. So here it is, an excellent choice.

The total length of the blade is 70 mm, and the thickness is 3 mm. The height of the blade varies between 19 mm and 16 mm.

The blade is, as it should be, completely flat-ground. It starts with a stock thickness of three millimetres that tapers down to a thickness of 0.4-0.5 mm behind the edge. The greater thickness is measured towards the tip.

The marking is discreet, and the Finch logo is found on the back of the blade

Speaking of tips, this one is unusually strong. Partly because the blade is very tall precisely in front, over the "hump". It is also first here that the blade starts to taper. This means that the tip works great for many small tasks, including puncturing thinner plastic and tape, etc.

But then this was a slip joint, so you shouldn't do stupid things like try to stab the blade into something; the risk of hurting yourself is then considerable. If you use the tip with a little discernment, it works great, though. Maybe it is a little too wide for my taste, as I like them to, among other things, pick metal chips out of fingers and hands. Yes, that is a common task for my pocket knives; I am a knife thrower after all. 

The blade, however, is otherwise extremely practical. That is the advantage of old blade types; they are tried and tested. This blade does not seem to have much of a curve, but the one that is there allows you to perform draw cuts against cutting boards, for example.

The straight edge works great for cutting anything that fits. By that I mean that it is a fairly small knife. The total edge length is around 63 mm. But if you stick to that, most things will be cut effectively. Especially since the knife is unusually sturdy for a slip joint.

Handle

Jumping Jack has a classically designed handle. Without a doubt, a nod to older times. It has a small "waist" at the front, which then widens to become a little rounder at the back. A curvy thing this. Incidentally, this also applies to the slightly arched sides.

The sides are both glued and screwed in place with two small T6. The frame and bolsters themselves are held in place by the adjustable pivot screw and a screw in the rear bolster. The size of the pivot screw is a notch up with a T8a. The fact that it is adjustable is significant for a modern traditional. An older knife would, of course, have been riveted. 

The handle is curvy with a steel bolster, frame and back spring

The material of the sides in this case is black and white resin plastic. Stylish but perhaps not the most exclusive. At the same time, it feels like a flirtation with the Cellidor plastic of the fifties. But if you want more exclusive sides, Jumping Jack is available in wood, blued bone and not least abalone. You know that green pearlescent material that comes from a special species of mussel.

The finish is excellent, making the frame and back spring feel like one piece.

Despite being small, this knife is built around a steel frame of a full two millimetres. The bolsters and the back spring are in the same material; this is a solid construction. You can tell by the feel when you hold the knife.

That brings us to grips. The length of the handle is 90 mm, and all of it is available surface for the fingers. The thickness amounts to 12 mm, and the height is a maximum of 21 mm. But with the rounded ends, it still becomes a three-finger knife for me, a good one, but not all fingers can fit.

A good grip, but it is a small knife, and of course, it gives a smaller handle

Not quite, anyway. In a hammer grip, it is close, but only half the little finger is supported and only if half the index finger is found in front of the handle. The three-finger grip becomes even clearer if the knife is held in a sabre grip. But then the thumb and index finger fall naturally into place in the depressions that form the "waist" of the handle. The rounded back end without protruding clips and the like is also comfortable against the inside of the handle. Overall, however, this is a very good and flexible handle given its size.

Walk and Talk

Instead of discussing "opening methods and locks" as I usually do, this is instead about concepts like walk and talk and stay and play. They are significantly more tied to this type of knife.

Accordingly, this knife is, of course, opened with two hands. For this purpose, there are double-sided nail grooves, which incidentally make the knife completely ambidextrous, but as a nail-biter, I am extremely grateful that it does not have to be used.

The knife opens with two hands and has nail notches to help. Jumping Jack also has a solid halfway stop

On the contrary, it is relatively easy to access the blade as about 7 mm of it protrudes and can be gripped in a pinch. I would rate the resistance itself as a seven, maybe an eight on a ten-point scale. The spring provides good resistance both on the way in and out, and the blade falls into place with a satisfying sound that gives some comfort to those who lack their lock. On the way in, there is a classic ninety-degree blade stop. A safety feature that means the blade on the way in does not cut off a fingertip as easily.

The action is unusually smooth for a slip joint. They certainly haven't gone so far as to have ball bearings, but unlike pure friction against the frame that was common in the past, the Jumping Jack has bronze friction bearings, which explains that detail.

Once out, the blade is solid. There is not a hint of lateral movement. In fact, the knife feels unusually sturdy for being this small. Should any slight play occur, you can always tighten the pivot screw.

There is no up and down movement either. As long as the spring holds the blade in place, that is. It is a slip joint after all. But on the other hand, if you put a lot of pressure on a blade in the wrong direction on a knife of this size, you have still done something wrong.

To Carry

Jumping Jack is a true pocket knife. No question about it. When folded, it measures 89 mm, and all ends are well-rounded and therefore soft. The only thing that could be perceived as sharp is the protruding tang.

A sheath can be purchased for the knife, but here we use one with a magnetic clip from another manufacturer

When the soft shape is then complemented by a nice weight of 90 g, there is not much negative to say about how the knife behaves in a pocket. It simply lies at the bottom. Preferably across if the size of the pocket allows. That is both an advantage and a disadvantage. But to remedy some of the historical problems that arose in connection with this behaviour and which resulted in questions like "how on earth can a knife disappear in a pocket?", the clip was invented. You will not find anything like that here.

That was the disadvantage; the advantage of clipless knives is that they are always more comfortable to work with.*

As you can see, the knife fits perfectly in this sheath

If you don't want to carry the knife loose in a pocket or bag, it's a good idea to buy the leather sheath that QSP has so aptly developed for this purpose. It also protects the knife's hilt from chafing if you also store other things like keys in the same pocket. This is especially true if you choose more exclusive materials like abalone, but even this resin variant can be scratched.

Now I didn't invest in a sheath because I have a couple lying around from another brand that I know are also great for this knife. 

To Conclude

For those who like the "modern traditionals" category, the Jumping Jack is not only a good example but also a really good choice. The look is there; what you think of it is, of course, personal, but the knife doesn't really look like everyone else. I see that as a big plus in a knife world where originality is sometimes in short supply. But here Mr Marquardt has managed to distil a classic model, but with a modern twist that at least appealed to my eye.

QSP has the nice habit of including a card that tells you the dimensions of the actual model in the box.

Then QSP has added a dose of what their name actually stands for. Written out, the acronym stands for Quality, Service, Price. I can't comment on the service in this specific case, even though it is generally very good. However, I can say something about the other two parts.

There are some classic quality markers for slip joints that can also be used to assess a modern interpretation of one. The first one, which applies to all knives, is, of course, how the transition between the different materials is made. This is especially true when you have designs that include bolsters. Here we also have double bolsters.

The work is really well done on this knife. It really exudes quality.

Jumping Jack, as elegant as an espresso

Another marker is how much, if any, light shines through the handle if the knife is held up to a light source. It is very difficult to get the spine spring completely tight to the frame. This is especially true of older handmade knives. With modern levels of tolerances, it is easier. On the Jumping Jack, nothing shines through. This, of course, gives the highest rating. Add to that the spring and frame are completely smooth in relation to each other, both with the blade in the extended and retracted position. It is very well made. Especially like the spring in the middle position, the ninety-degree stop, also here at the same height as the frame. A finesse that is only found on very fine slip joints. 

Then you have the usual folding knife pitfalls to avoid. These include areas such as how the factory edge is made, whether the blade is centred when the knife is closed, whether there is play in the blade when the knife is open, and so on.

QSP has succeeded on all counts with the Jumping Jack, and it is not hard to see why other brands are starting to use QSP as an OEM manufacturer. This is a damn well-made knife.

The QSP Jumping Jack is a truly classic pocket knife, easy to always carry with you.

So if you appreciate the design language and like QSP as a brand, Jumping Jack is a more than viable alternative. Especially if we mix in the last letter in the name and talk about the price. The recommended price on the website is 75$ and when it reaches European stores, the price is from 99€.

For the invested pennies, you get a real quality knife with a timeless design and well-chosen materials. It is highly recommended!
