Ugh. I’ll just agree with what Preston and Steve said about that on MMR yesterday: “Can we uninvent that, please?”
(They were talking about officials in England being worried that gangs and such were going to start using them.)
The idea of something that can inject you with cold expanding air just squicks me out.
I’m gonna get me one, and I’m gonna coat it with poison. That way, I can kill people three times as dead with just one stab! Awesome!
They wouldn’t’ve had so much trouble with Rasputin had those things been around back then…
And then we need gas canisters filled with hydrogen.
We can stab, poison, expand and ignite the target.
I wonder if they make one with canisters of angry bees?
Now they only need to make a sword-sized version.
(Why, katana for preferance, thank you, but I’ll go for the flamberge if you have nothing else)
These would make wicked science-fiction / outer space hand to hand combat weapons. You nick the other guy’s suit, he’d perhaps be able to patch it, or perhaps his suit is self sealing, but …
-POW-
…you inflate his suit with a basketball sized bolus of gas, (+/- angry bees) shredding his suit and decompressing him.
And if you’re really in a bind, you could use the gas as an impulse engine to zoom around short distances in space.
I’ve submitted my patent for the deer-hunting arrow version, with teriyaki marinade suspended in the C02
Teriyaki and bees? Or do you want to consider honey-mustard and bees.
Damn, now I’m hungry.

I can’t decide if that’s brilliant or stupid. Hell, I can’t decide if it is real or a whoosh.
I also can’t get the vision out of my mind of being accidently shot, a la Dick Cheney, and lying there thinking “Sage? Why do I smell sage?”.
I think the garlic shot should be a staple in each self-respecting vampire hunter’s arsenal.
I saw the CO2 reference and I thought it turned the blade into a bullet – that it actually fired the blade some distance into a target. Then I watched the video.
I like my idea better.
Finally, a knife you could bring to a gunfight!
There’s a news story on this knife here.
I started a thread on it after having failed to see this one.
There are right hands for this knife? 
Hey, I remember Edward Woodward killing Adam Ant with one on those on “The Equalizer!”
Watch the movie the Sword and the Sorceror. It’s set in one of those Conan-like Hyborian ages, and the hero has a three-bladed sword , two of the blades of which seem to be jet-propelled !!!
(Using Hyborian Age CO[sub]2[/sub] canisters, I guess.)
