Wow - I believe I have found better weapon for my car than illegal brass knuckles. The law wants the worthless degenerates of society to have the upper hand thus making brass knuckles illegal.
I can keep the lock and sock separate but close and smash the faces of anyone dumb enough to mess with someone they do not know.
My friend got hit in the head with a cue ball in a sock once when he got jumped so he started using this tactic for self defence. I'm surprised a lock works better!! Hahaha
