Hapkido, also spelled hap ki do or hapki-do, is a Korean martial art. It is a hybrid form of self-defense that employs joint locks, chokeholds, throwing techniques, kicks, punches, and other striking attacks. It also teaches the use of traditional weapons, including knife, sword, rope, nunchaku, cane, short stick, and middle-length staff, gun, and bō (Japanese), which vary in emphasis depending on the particular tradition examined.
