I got this from a fellow officer. This thing could blow you up like the Pop-n-Fresh Doughboy. Staying aware of what's out there is half the battle!! Stay Safe. Officer Safety Item Officers should be aware of this knife. You might survive a stab wound with an ordinary knife, but this one would be fatal. It delivers CO2 into the body at 800 PSI. It freezes all the organs the gas reaches and causes massive damage. The knife is available for $499.99 on the internet. http://www.waspknife.com/ "This weapon injects a freezing cold ball of compressed gas, approximately the size of a basketball, at 800psi 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. When used underwater, the injected gas carries the predator to the surface BEFORE blood is released into the water. Thus giving the diver added protection by diverting other potential predators to the surface." New Video!
