The knife fits very well in the hand and is extremely handy, with an ideal length, and the fit to the sheath is also perfect. Visually, it makes a much better impression than in the photos, it really is pleasing to the eye, which I also consider important. I recommend it.
Za-Pas WZ.25 Grom Fixed Blade Knife - Black
The WZ.25 Grom knife, created by Militaria.pl in collaboration with military personnel and outdoor specialists, is manufactured by the esteemed Polish company Za-Pas. Engineered as a robust tactical tool, it features a 15-centimeter blade with a Clip-Point profile and a Full Tang design. A key strength of this knife is its blade, crafted from premium Swedish Sleipner steel and subjected to expert heat treatment. The handle, equipped with contoured G10 laminate scales, guarantees superior ergonomics and resilience. Included in the package is a sheath made from impact-resistant ABS plastic, suitable for belt carry, along with a versatile mounting system for gear attachment.
Sleipner tool steel
The WZ.25 Thunderer is forged from a single piece of Sleipner tool steel crafted by the renowned Swedish steel producer Uddeholm. Offering exceptional wear resistance along with outstanding toughness against cracking and chipping, Sleipner steel achieves a balance rarely found in steels intended for intensive use and combat blades. Corrosion resistance is also notably higher compared to standard low-alloy tool steels, making it particularly suitable for demanding outdoor and tactical scenarios. The name Sleipner draws inspiration from Norse mythology, referencing the legendary eight-legged steed ridden by Odin, the god of war and warriors.
Geometry and hardening, flat grind, bolster and notch on the spine
Featuring a Clip-Point blade profile with a length of 147 mm, the blade is hardened to 59 +/-1 HRC and finished with a black, textured coating to maximize corrosion resistance. The blade is flat ground halfway up, and together with the 4.3 mm thick spine, provides exceptional strength while ensuring excellent cutting performance. Thanks to a reinforced tip profile, the risk of tip breakage is greatly minimized. Strategically placed jimping (notches) on the spine offer enhanced thumb grip, enabling superior control during cutting tasks. The remaining single-sided bolster poses no hindrance to use, while the index finger groove delivers effective hand protection, even during powerful thrusts.
G10 laminate handle lining, security cord hole
A handle crafted from ergonomically contoured G10 glass-epoxy laminate scales is firmly attached to the tang with screws. The cladding's matte finish offers a reliable, non-slip grip, even when hands are wet or dirty. A lanyard hole is positioned at the end of the handle, enabling the use of a securing cord.
Strong ABS holster with multi-position attachment
The kit features a rigid holster crafted from lightweight, impact-resistant ABS plastic. Multiple holes and grommets on each side facilitate versatile mounting options to gear. A nylon belt loop, secured with a steel plate, provides exceptional stability and enhances the overall durability of the construction.

I had the opportunity to use the WZ.25 Grom Black during SERE-B. After this experience, I can say that it is a solid and practical outdoor knife. It performed well in typical field tasks, and the Full Tang construction gives a sense of durability and confidence during use.
-
A solid piece of knife, and to my amateur eye it looks pretty good. The stonewashed blade looks great. As for the workmanship, there’s nothing to complain about. The only thing that doesn’t suit me is the thickness of the handle. I don’t know if it’s intentional so that a commando wearing gloves can hold it comfortably, but I’m not a commando and for me it’s a bit too thin. Bought for 249 PLN.
-
The knife sits securely in the hand, whether you're working with gloves or without. It is quite light, which is a big advantage if the work drags on. The jimping on the spine of the blade provides good thumb support and makes working with the knife much more comfortable. The knife performs well in "ordinary" camp tasks, and it handles batoning fairly large pieces of firewood very well. The black protective coating definitely requires an additional protective layer to be applied, most likely some kind of oil. Without it, it probably won’t last long — my specimen already shows wear from ordinary batoning — so it should really be one star lower for that, but it doesn’t matter much to me, so I’m leaving it at 5. The knife fits the sheath well, with no looseness. Bought on sale, so there’s really nothing to complain about. And a Polish manufacturer is always appreciated. I recommend it.

I highly recommend this knife, it is very durable. Thanks to the 25-degree edge, it keeps its sharpness for a long time, and when it gets dull, it is enough to run it over a 600-grit diamond, then finish it on a 1000 or 1500 stone and it is razor-sharp again. My only reservation as a left-handed person is that if you switch the belt attachment to the other side, it is unfortunately arranged in such a way that it squeezes the sheath, so the knife goes in very tightly and during use it will get scratched too much and the coating or finish of the blade will be damaged. لذلك I recommend left-handed users get some kind of Tek-Lock or, if you have a Cold Steel knife such as an SRK or GI Tanto, move the belt attachment to our Grom and use the Za Pasa attachment for the Cold Steel. The Cold Steel will still fit in normally, and I also tested it on my own knife with the Cold Steel belt attachment and it works fine, so I recommend this solution

The knife immediately makes a very good impression with its solid craftsmanship. It fits well in the hand, and the handle provides a secure grip even during prolonged use. The blade is carefully made and feels very durable. The stonewashed finish looks great and additionally gives the knife character. The sheath is practical and allows for convenient carrying of the knife. This is a very successful model for people who appreciate solid and aesthetically made equipment.
-
Very good, durable. As for the engraving: done perfectly in the color of the manufacturer's marking - a fairy tale. Perfectly integrated. I’ll say this right away: buy a whetstone and oil - don’t skimp. And it’s a Polish product!
-
The knife gives a very good impression in terms of craftsmanship – it is solid, fits well in the hand, and works both outdoors and for heavier tasks. The blade stays sharp for a long time, and the sheath is comfortable and practical to carry. The order was processed quickly, and the product matched the description.
-
WZ-25 Very nicely made, durable, sharp right out of the box. Worth recommending and its price. It's my first knife of this kind. I'll see how it holds up in a few years :D
-
The WZ-25 is my ideal long-awaited forest knife. It fits perfectly in the hand, is hefty but not clumsy. Slipner steel holds sharpness very well, and the blade itself gives you a sense of complete control during cutting and heavy-duty tasks. The handle is ergonomic and secure, even with a wet hand. The sheath is well-made and holds the knife firmly in place. This is a tool you actually want to take to the forest and use without worry that something will overwhelm it. An ideal choice for someone who needs a strong work knife – without frills, but with real functionality. I recommend it.
-
I definitely recommend it. A thoughtfully designed and well-made knife. Paired with the sheath, it looks like a tactical knife, but when you take it in your hand, you can't help but feel that it is a very good bushcraft or survival knife. The balance, weight, size, and shape of the blade along with the handle make the knife literally rotate by itself in your hand. The handle is perfectly finished, and when you look closely at the details of the blade (guard and jimping) along with the stonewashed finish, the Za-Pas WZ.25 knife takes on a handmade character. The ABS sheath is well-fitted and finished - no burrs or sharp edges. Of course, the biggest advantage for me is that it is fully Polish-made. It turns out that the Za-Pas WZ.25 is an excellent knife.
-
The knife, despite lacking any special contouring, fits perfectly in the hand. You can feel the solid workmanship; it sits well with the sheath. Sharp from the factory, good thickness, and the sheath is quite flexible so it does not get in the way when sitting if mounted on a belt.

Za-Pas WZ.25 Grom Stonewashed Knife - Black - A solid piece of knife, and most importantly made of Swedish Sleipner steel. Despite not having a very bulky handle, the knife sits well in the hand, and the build quality is decent. It performs very well in camp tasks; it is practical and sturdy. During longer work, the low-comfort and very uncomfortable jimping is a big drawback! But that is the only thing I can complain about. I recommend this knife.
-
The packaging should say: "Warning, this is not just another toy from China, nor an object resembling a knife. This is a real knife. Use only under adult supervision". If anyone actually received some defects/poor fitting, etc., I sympathize, because my piece arrived in perfect condition. Any comparisons to the Cold Steel SRK (in the AUS8 steel version) are a mistake, because despite a similar price, at least at the time of my purchase, here we are dealing with gear several classes better. The steel holds an edge phenomenally well; even after heavy use on wood, it shreds a can of that well-known drink into strips. Generally, we are getting custom-level workmanship at the price of a budget production item, and whoever missed the promotion is out of luck. Mr. Daniel Pabiś and his team are doing a truly damn good job. Below is a photo of the SRK after slight modifications and more than a decade of use, next to the wz 25.

The knife is practically indestructible. It handles heavy camp work perfectly, such as batoning wood or prying. The handle is well contoured, and the texture of the scales ensures that the knife does not slip in the hand. The matte, irregular Stonewashed blade finish hides scratches very well. I recommend it.
