We all remember how cool it was when Chief Brody literally blew up Bruce the shark at the end of Jaws. (Oops, that should probably have had a spoiler alert.) But what if you happen to find yourself in a similar situation without a sinking ship and a tank of compressed air? I’m sure that same thought was going through the head of whoever invented the WASP diver’s knife. The knife features a small tank that “injects a frozen ball of compressed gas approximately the size of a basketball at 850psi nearly instantly.”
While it’s able to bring down a large land predator, it seems even more effective while diving, where a shark or other underwater attacker will be immediately carried to the surface before any blood is released into the water. And when the blood is released, other predators will be drawn to the surface instead of towards the diver in peril. The WASP knife is rumored to have a price tag of about $400, but there’s a pretty good chance it won’t be sold to civilians.
Also, is it just me, or does that cutaway diagram have a weird, optical-illusion thing happening? Looking at the butt of the knife and the top of the small gas canister, I can’t really tell which way the knife is supposed to be pointing.
