The first “anti-stab” knife is to go on sale in Britain, designed to work as normal in the kitchen but to be ineffective as a weapon. The knife has a rounded edge instead of a point and will snag on clothing and skin to make it more difficult to stab someone. It was invented by industrial designer John Cornock, who was inspired by a documentary in which doctors advocated banning traditional knives. Mr Cornock, 42, from Swindon, said that the knife will cut vegetables, but will make it almost impossible to stab someone to death and will reduce the risk of accidental injuries.
