When just stabbing your enemy isnt enough, this injection knife the "WASP" packs a nasty and instant 800 psi air burst that is extremely lethal.
Original designed for divers to protect against shark attacks. Different versions exist one with Co2 power and one with custom made bullet size blasters (above).
The co2 version of the injection knife, as seen above, delivers a freezing blast of the compressed gas and the internal damage it does can and will kill almost anything by damaging organs and forcing air into the blood stream.
Price tag on this crazy knife is between $400 and $600 depending on where you buy it and what accessories you want. the best place to buy this is probably from the manufacturer. Check out WASP injection knife. That is the original creators website.
There are many variations of this knife and different colors to choose from.
I also saw a very stylish wooden handled version.
