This is the world's most useful knife, and if it’s used on someone, it could cause serious damage. It's called the Wasp Injector Knife, and it was made for divers to defend themselves from sharks. The knife has a special hole in its blade that releases CO2 gas from a small bottle attached to the handle. To use it, you just stab the knife and press a button, and the gas shoots out with 800 PSI force, which is strong enough to make a shark flee or cause severe injury to an attacker.
