A Very Effective Survival Knife

WASP Injection Systems, Inc. - WASP Injection Knife

Scary. Imagine getting stabbed on the street with one of these.


"
As divers, we all know what the effects of compressed gas are underwater. Our training teaches us that our lungs would burst from over-inflation if we held our breath and rose to the surface. This principle is key to the effectiveness of the WASP Injection System.
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. 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.

Kind of sounds like the scene in Live and Let Die when Bond shoves that gas pellets into the villains mouth...
