The fixed blade knife is a good standby. Recently added a Tomahawk to my collection, my wife thinks I'm going flashback to "Last Of The Mohicians". Louisville slugger is good, and so are the little ones sold at the ball fields as souvenirs. Length of chain w/ padlock on the end, claw or straight hammer, crowbar, and the "Handi Bar", pepper spray, fire extinquisher, piece of black pipe, etc. all lethal if struck. Lots of ideas.
