Kuk sool won is a traditional korean martial art, formulated as a distillation of the korean arts practiced historically.

The main branches of kuk sool are buddhist martial arts( bulkyo mu sool, emphasizing ki training, circular motions and blunt weapons ), royal court martial arts (koong joong mu sool, emphasizing single and double swords, fans and long bladed weapons )and family or tribal martial arts( sado mu sool, including arts that evolved from hunter/gatherer activities such as stone throwing and traditional korean wrestling).This style is a result of the studies of founder Suh In Hyuk, grandson of the last instructor for the Korean palace guard.
