However...

I was talking with a fire-eater at a renaissance faire a few years ago who claimed to have had one of those "Crocodile Dundee 'That's not a knife, this is a knife!'" experiences. He said he was busking in some city in the wintertime and was wearing a long cape over his usual costume which included a cutlass. The punks who tried to roll him for the money he'd collected during the day changed their minds when he flipped his cape back and nonchalantly pulled 24-inches of silvered steel from his scabbard.

Those Ren Faire and SCA people do like to play with knives.
