Approved by the Home Office in the UK, this anti-stab knife is seen as a potential panacea to the spate of stabbings in the country. It's been designed by John Carnock, after his wife saw a TV report calling for a ban on long, pointed kitchen knives. Although he admits there's no such thing as a safe knife, he claims of his design: "the idea is you can't inflict a fatal wound. Nobody could just grab one out of the kitchen drawer and kill someone."
Resembling the underside of a ship, the $80 knife has a blunt upper protrusion, with an undercut that protects the blade, and whilst it may prevent a mortal stab wound, there's still plenty of scope for it to do some pretty nasty damage. It is expected to go on sale towards the end of the year, but do you really reckon it will bring the number of fatalities down — 322 people died in Britain last year as a result of knife crime — if it were universally available?
