Israel have been faced with daily stabbing attacks by Palestinians in the recent weeks.
Eitam Lachover who works for the state broadcaster was asked to try on a stab proof vest and demonstrate a serious stabbing in the back.
After a few stabs one actually goes into his spine. He was however not seriously harmed requiring a few stitches in hospital.
Yaniv Montakyo, a vice-president of the company that designed the vest, told Channel 2 TV that Lachover was stabbed through a part of the vest that had no protective material.
An earlier take will still be used for the broadcast.
