Yeah, dude. I have a 1930's police truncheon that looks like a walking stick with a knob for your hand, but on the part close to the ground there is a hole bored through with a leather wrist loop to convert it into a club with a quick flick. I have two actually. Identical but one has a lead plug on the business end. Unless truncheon is a euphemism, then you'll have to buy me a drink first
