Do you know what is the greatest damage which a knife can cause to your body? A small wound or a minor injury? Now, there is one new knife which is given the name Wasp, is going to change your perception about what a knife can do.

We all know that knife can not be more harmful compared to a gun. But you are wrong. A shot from a gun can not kill a crocodile or a dinosaur ( if there is still a dinosaur alive today), but Wasp might be able to do it, and it is only as small as any normal knife that you have in your kitchen.

Wasp might look as small as a normal knife, but it is totally different if you look at the structure inside the knife. In beneath the thin blade of the knife hide a small passage which is linked to a highly pressurized cylinder stored inside its small handle. The knife is able to inject a highly pressurized frozen gas which will blow a big hole on your body at a press of a small button on the knife. The hole might be as a big as a basketball and all your tissue and organ in the affected area might be frozen.

Below is a video which shows you how the knife is used on a watermelon. You can see clearly how great is the damage caused by the knife which breaks the watermelon into small pieces.
