There's a new knife on the market that can explode internal organs. Called the WASP knife it was designed to kill sharks and bears. British police are now on the lookout for it.
Police are concerned that the weapon could fall into the wrong hands.
Made in America the blade has a needle in its tip that injects a frozen ball of gas.
The gas instantly freezes all tissues and organs in the area blasted by the gas.
"This knife will almost certainly kill and the Met must have intelligence that they are in circulation.
"I think it is only a matter of time before one of these is used because the internet makes it much easier to find and buy weapons like this."
Labour MP for Perry Barr in Birmingham, Khalid Mahmood, said: "Weapons like this are absolutely disgraceful and there is no reason at all why people should be walking around the streets with them.
The manufacturer says it is the perfect weapon for downed pilots, soldiers and security guards. It is said to be able to drop many of the world's largest predators. It sells for $379.00 and is patented to
