learn to use a stick … cant outlaw those.
coins for parking change + your sock= sap
roll of coins in your hand one punch
credit card.. cuts like a knife if you know how.
set of steel stress balls or fill plastic ones with a surprise.
you can get nice belts made of all kinds of useful things to hold up your pants.
get a carbon fiber arch support and sharpen one edge
get a man purse and put a heavy object in it such as coins for parking change.
in office… can have a golf club+ball and a putting green cup.
vehicle heavy jumper cables, tire iron, lubricant spray, flares, sand
baseball bat glove and ball…going out for some fun with the family. a team shirt will erase all doubt from a beer league.
just use your imagination as said above.. it is more about YOUR SKILL and attitude than anything else.
