Yeah, i mean if someone really wants to decapitate someone they can just go to the next best hardware store and get a chainsaw.

Butter knife ‘an offensive weapon’

A butter knife can be an offensive weapon, the High Court ruled yesterday.

The decision came in the rejection of an appeal by Charlie Brooker, of Welling, Kent, who had been convicted under the Criminal Justice Act of carrying a bladed instrument.

Mark Hardie, appearing for Brooker, argued that the knife had no handle, sharp edges or points and therefore could not fall foul of a law intended to protect people from dangerous weapons.

But Lord Justice Laws, sitting with Mr Justice David Steel, disagreed. He said: “I would accept that a sharp or pointed blade was the paradigm case - however the words of the statute are unqualified and refer to any article that has a blade.”

I will bet you that Parliament would be willing to impose a ban on possession of a chainsaw without just cause.
