Not as cool, a straight claw hammer. I'm not police, I'd thing if you were hauled in court, the hammer would look more like it was used for self defense than a fancy billy club.
Grandfather was a carpenter for a large builder back in the 60's. They were doing a big job in a terrible neighborhood. Guy told GP to keep a claw hammer on the seat of his truck cause they will try to dive in at stop signs. He did. He said one day on the way to the job a skinny fellow of color jumped in the passenger window with a knife. He said 3 quick thumps with a 24oz hammer changed the guys mind real fast. That day he went home turned an about inch and a half dowel on his lathe about 18 inches long. Drilled out the end and filled it with lead than capped it real nice like and fire hardened it so it looked nice. Till the day he died it was under his bed. U could cave a mans head in with that thing for sure.
