The three knives detailed here were sold to me by Noah Walt of Thrust Magazine, who was responsible for bringing them to market. Each has a blade of 01 tool steel with a baked-on black coating, leather handle wraps, and Kydex sheaths from Eric at On/Scene Tactical. The largest, the “Jak Dao,” is a collaboration with noted self-defense instructor James Keating. The ring-handled blade is called the “Skinny Puppy,” and the Wharncliffe-inspired blade is the “Beatle-juice.”
All of these knives are purpose-built self-defense tools, really, so I’ve not done extensive cutting tests with them. They were sharp, they cut nicely, and they penetrated nicely in initial testing, but these are blades meant to be carried as weapons first and foremost. As such I’ve not done much in the way of extended cutting to test the durability of the tool steel. Rather, I’ve done enough cutting to satisfy me that the knives will perform for self-defense, and have since carried all three extensively.
The baked on finish has held up reasonably well, though it wears around the cutting edges and has scuffed where the knives rub most actively against the Kydex while sheathed.
The friction-fit On/Scene Tactical sheaths allow for multiple carry positions, right- or left-hand. The belt clips with which they ship are perfect for Inside the Waistband (IWB) carry. The knives snap positively into the sheaths and, while they shift a little inside the sheaths, are secure and will not fall out even while making violent physical movements. I’ve had sheaths made for me by Eric at On/Scene before and I have never been unhappy with the results.
The grommet-equipped sheaths could also be used with paracord to form one’s own shoulder harnesses, or with a CRKT-manufactured MercHarness for the same purpose.
The Beatle-Juice is a compact “two- to three-finger” cutter that would serve best as an emergency slashing tool. It can be used to pierce, but my thumb naturally gravitates to the top of the blade and the knife handles best when cutting and slicing. The contours of the knife form an integral guard, of sorts, ahd there is a hole in the butt for attaching a lanyard. (I actually removed the lanyards from my knives.)
The cord-wrapped handle is a little uneven but comfortable. It provides decent traction. The knife overall is quite ergonomic despite the fact that’s quite small for my fat hands, because my fingers fit into the curves of the blade in all the right places.
In cutting, the generally underwhelming Wharncliffe-style blade is helped by the slight curve it posses, which gives it… I don’t know, let’s call it “reverse belly” for carving its way through the cutting medium. It really is an impressive little slicer, which belies its relatively benign appearance.
The Skinny Puppy is a much more severely curved slashing and thrusting weapon, named for the relatively minimal handle. Retention of that skinny handle is helped greatly by the finger ring at the tail (which is something you’ll either love or loathe). The leather-wrapped handle, like the handle on the Beatle-Juice, is comfortable if a bit uneven, and it provides good traction.
The curves of the knife again make my hand want to slip into very specific position, with my thumb on the slope just ahead of the handle portion of the spine. Thumb grooves would be welcome here, but the knife is no less secure in my mitt for the lack of them. There is no guard, but the sweep of the blade forms an almost-choil forward of the handle that should keep your fingers away from the cutting edge.
The Skinny Puppy is all belly and needle-tipped point, making it an excellent slasher, slicer, and penetrator. Resist the temptation, however, to perform kerambit-style twirls with the tail ring, for I can see no way to do this in safety and the knife really shouldn’t be used for that.
My favorite of the trio is the Jak Dao. Jim Keating’s influence is obvious. the knife is a fighter, with features designed to make it a good carry piece.
The handle is intentionally small, but not too small to afford a good grip. This lowers the knife’s carry profile; the blade-to-handle ratio favors the blade by a good percentage.
There is again a sort of integral guard (though no true protruding guard), but the thumb-ramp curve of the Jak Dao has the thumb grooves for which I’ve been wishing on the other two blades. Thanks to the way the swell of the butt (it forms a sort of enlarged, flat circle) fits in my palm, the knife also feels very well balanced in my hand, and it is very secure. Traction of the somewhat uneven leather-wrapped handle is good, but the true sureness of the grip here owes to the shape of the knife and how it fits into the palm.
The cutting edge is a long, gently curved arc that features a straight, sharpened false edge. this makes the Jack Dao an excellent slasher and a brutal penetrator. It also allows for back- , snap-, and comma-cuts (which one would expect from a knife James Keating had a hand in designing)
If the Jak Dao has any drawbacks it is that it is deceptively long, meaning it is not quite as comfortable in the waistband as the user might first be led to believe by the appearance of the low-profile handle.
Conclusion
All three of these knives are excellent purpose-built defensive tools. They handle well, they cut well, and they have held up under extended on-body carry. I have been pleased with my purchases and will speak well of Noah Walt and Thrust Magazine in the future.
