Anything can be a weapon, if you see a bunch of dudes when you are out and it looks like it could get lively it’s as simple as lighting a fag and pushing in the first dude eyeball.
There a murder case going on at the moment for a young lad from my old town, got hit on the head with a plasterers whisk and died.
Obviously you don’t now ban plasterers whisks and that logic should apply across the board.
