Here’s a really cool diving knife that injects 850 PSI of compressed gas into your predators whether that’s a Tiger or a Shark, it will freeze them instantly. Just don’t stick it in humans. (That’d be BBAAADD)
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.
