Are you going to walk around with a billy club? Why not use a cane? You can get one with a metal ball or a skull and you may be able to use some staff techniques. I commented here on the dowel/closet rod BUT that wood is SOFT. Use a shovel handle if you must..... a pick handle fits my hand better. You can also go to a truck stop and get a "tire checker" OR, they sell "fish clubs" at bait and tackle shops. What I recommend is a Slap Jack and put it behind your wallet. BUT...... Please check with your local and state officials on the legalities of this matter!
