A fine example to us of the combination of hoplophobia

and stupidity:
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.
Of course, if you need a point for something in the kitchen you'll have to use another knife. Unless the socialist hoplophobes decide to ban all 'non-anti-stab' knives, in which case they can take a break from making sure you have a license to watch tv and instead go through your kitchen to make sure you don't have an old knife around.
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.
Unless you really drive it in. Or just cut their throat or do other slicing with it.
He said: “It can never be a totally safe knife, but the idea is you can’t inflict a fatal wound. Nobody could just grab one out of the kitchen drawer and kill someone.”
Again, unless you drive it in really hard. Which murderers and such undesirable types tend to do. Or just grab it and start cutting(yes, I'm sure somebody is trying to figure out how to force people to only own dull knives).
The knife is expected to sell for around £40-50 and has been tested with “very favourable” results by the Home Office’s Design and Technology Alliance - set up to research products that can deter crime.
So, in the name of a 'safer' knife, they want people to spend $90-100 on something that
A: has no point, which is a useful sort of thing on a knife,
B: can still cut,
C: can, with a few minutes time, receive a bright, shiny new point suitable for puncturing all kinds of things.

You know, seems it would be a lot simpler to, say, capture violent criminals and lock their ass up for a LONG time, than to keep blaming objects for what the criminals do...
