What is Haidong Gumdo?

Haidong Gumdo ('Way of the Eastern Sea Sword') is a modern Korean sword martial art formalised in 1982 by Kim Jeong Ho + Na Han-Il, claiming lineage to ancient Goguryeo warrior traditions (historical continuity disputed by scholars). Three competition disciplines: Bonguk-geombeop (solo forms), Bemgi (target cutting on rolled straw or tatami mats soaked in water), and Gyeokgeom (choreographed multi-opponent sparring with wooden swords). Distinct from Kumdo (Korean Kendo) — Haidong Gumdo uses no armoured sparring but does include live-blade cutting at black-belt level after 3-4 years wooden-sword training. Governed by World Haidong Gumdo Federation (WHDGF, founded 1996, HQ Anyang, South Korea) with 50+ member countries; also active European Haidong Gumdo Cup since 2003.
