In a few previous posts I’ve made much about how the Japanese kunai had undergone an amazing transformation at the hands of Hollywood, from a cheap, multi purpose garden implement into the omnipotent Swiss Army knife of the Shinobi warrior. The modern replica kunai is now part throwing knife, part parry tool, part fighting knife, camp knife, hunting knife, scalpel, the list goes on… Well, the point of this post is that I found yet another incarnation of kunai, from veteran knife shop Cold Steel…:

Cold Steel Kunai

Now as Kunai go, this is fairly recognizable, though it is a rather unique design, and a major departure from the traditional Kunai design in two very important ways.

First, the blade is a flat, wide triangular blade. Your traditional Kunai was more leaf shaped, than actually a triangle, though this is not a bad approximation. This also stays in keeping with the diamond shaped blade cross section, which gives the kunai a lot of strength, though it is much more shallow diamond than some traditional designs. It would make a strong thrusting weapon. Not so much for cutting, even though it has two very sharp edges. Kunai really weren’t the best design for cutting. Too short and too wide.

The second design departure is, to me at least, a much more important one. In defiance of the traditional full tang Kunai construction, Cold Steel has seen fit to simply encase a tang in a kraton handle. Yes, it looks cool, it probably provides a great grip, and it’s got this great tactical ring on the end of it, but this, imho, is a grave mistake.

There is simply not as much strength in a grip molded onto a rat tail as there is with a full tang with scales. given the kind of use that a kunai might see, i would always be worried about the tang somehow working it’s way out of the grip material. I’ve seen it happen too many times. And it’s a great shame.

But speaking of different kinds of uses, I couldn’t help but notice the handy little chart that cold steel provided on the different grips that could be used to wield the kunai. Now I will readily admit that I am no kunai fighting expert, but seriously, half of those grips seem very… well… pointless… It looks almost like they just held it in as many ways they could think of and then picked the coolest looking ones for the pic.

I mean seriously, a kunai is not a punch dagger. Punch daggers are short for a reason. You don’t want the blade rotating out of your hand. That is why grips 1 and 6 fail miserably in that respect. And grip 4 is pointless when you could use either 3 or 5 to accomplish essentially the same reverse/ice pick grip in a much stronger way. Grip 8 is a good strong hammer grip, while 7 looks like a good way to break a pinky. And whoever came up with grip 2 must have been smoking a controlled substance…

In fact I’m thinking the only ones who could find any practical use for grip 2 would have to be Ninjas… But you can try it for yourself if you feel so inclined… I’m just saying…
