Knife not only stabs a person but injects them with C02 - amazing
This knife has a C02 cylinder in the handle and a small vent near the tip of the blade. Stabbing an object triggers the C02 cylinder which then
injects it into the victim.
Great for fighting off sharks, but it would be really handy for cooling your beer!
Just stab through the top of the can and push the button :)
This weapon injects a frozen ball of compressed gas
approximately the size of a basketball at 850psi nearly instantly.
The effects of this injection will drop many of the world's largest land predators. The effects of the compressed gas not only cause over-inflation
during ascent when used underwater, but also freezes all tissues and organs surrounding the point of injection on land or at sea.
