To those of you who train with knives for combat purposes...here is an interesting knife that may be beneficial for whatever dangerous situations you find yourself into!
Introducing the WASP Knife: http://www.waspknife.com/
I do a ton of knife training and I'm not for sure on how well the release valve opperates but it doesn't look like it has any blood grooves, so that may be designed to help it "stick" so that you have a second to push the release button. Still, interesting to see and very, VERY deadly to even the most novice user!
Add this weapon to your skills and you're going to have a deadly tool. To me this is simular as to having a knife with a 12ga inside it (it just won't expale fragments and shot). The only thing I see so far that I don't like is that it doesn't really have a hand guard at all and that could really hurt. Other than that...???
I'm thinking I might order one of these little devils to see how well it truely performs...if I'm not satisfied, can always get your money back (supposidly, lol).
Thought it was interesting....
