Virtually anything can be used as a weapon, including things found in one's environment. Always be aware of your surroundings, keeping alert for any items that can be used to your (or your opponent's) advantage. Make sure to have a few simple things readily at hand such as keys (grasp the chain or ring in your palm with the keys extended between the fingers of your fist), a sturdy comb (great for jabbing and gouging sensitive exposed areas like the face and neck), most beverages (if not damaging, can at least create a momentary diversion), a belt (swung like a whip, the buckle can shred), etc. Useful things in the fight area may include rocks, bricks, boards, tree limbs, trash cans, glass bottles, or other items.
