Half-brick in a sock
This is a formidable weapon in the right hands. It's not a weapon that can easily be wielded by holding it with your feet, even when your hands are full of swords and monster bits. With some careful aiming though, even the toughest monsters can be given a real fright using this weapon, although there is little likelihood of actually killing anything with it unless you have 10 or 12 of them in use at the same time.
Warning: socks must never be worn when they contain half bricks.
