Hapkido (UK: /ˌhæpkiːˈdoʊ/ HAP-kee-DOH, US: /hɑːpˈkiːdoʊ/ hahp-KEE-doh, Korean: 합기도; RR: hapgido; pronounced [hap̚.ki.do]), 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, grappling, chokeholds, throwing techniques, kicks, punches, and other striking attacks. It also teaches the use of traditional weapons, including knife, sword, rope, nunchaku (ssang juhl bong), cane (ji pang ee), short stick (dan bong), and middle-length staff (joong bong), gun (analogous to the Japanese jō), and bō (Japanese), which vary in emphasis depending on the particular tradition examined.
Hapkido employs both long-range and close-range fighting techniques, utilizing jumping kicks and percussive hand strikes at longer ranges, and pressure point strikes, joint locks, and throws at closer fighting distances. Hapkido emphasizes circular motion, redirection of force, and control of the opponent. Practitioners seek to gain advantage over their opponents through footwork and body positioning to incorporate the use of leverage, avoiding the use of brute strength against brute strength.
