Punji Sticks

The punji sticks or punji stake is a type of booby trapped stake. It is a simple spike, made out of wood or bamboo, which is sharpened, heated, and usually set in a hole. They are banned by the Geneva Convention. Punji sticks are usually deployed in substantial numbers. The Oxford English Dictionary (third edition, 2007) lists less frequent, earlier spellings for "punji stake (or stick)": panja, panjee, panjie, panji, and punge.
