That's pretty scary stuff right there... How long will it be before some scumbag uses one on a person?

Soon. sooner than you think probably, since this thing has been on the market for several weeks now, and already got around to all of the "Urban Warrior" type forums...

THat thing is terrifying.. Just when you think "Well hey, at least I was only stabbed instead of shot... ...boom". Yuck.

it looks like a nife with a Co2 canister in the handle..........

Made in America, from what I understand.

Correction..... conceptualized in America, possibly made in "Foreign Country."

I think an anti-shark bang stick would work a hell of a lot better.

I always thought these knives were made for anti-shark defense too. Been around a long time haven't they?

If anyone would have bothered to read the webpage, they would see that, yes, it was originally built for divers as protection. It's was secondarily built as last chance protection in the wild while among Big Scary Animals. It was then mentioned in passing that, yes, it possible could be used to kill a person, but that it was never meant for that. There's examples, tech drawing, all sorts of stuff there which would answer any and all questions posed in this thread.
