The concept of Kyuki-Do was first introduced to the United States by Grand Master Ok Hyung Kim in 1967. Kyuki-Do synthesizes the techniques of Tae Kwon Do, Judo, and Hapki Do. These three arts represent the core or foundation of Kyuki-Do. They are, however, not the only Martial Arts included in the Art of Kyuki-Do. Much like Bruce Lee’s Jeet Kun Do, Kyuki-Do is constantly evolving, new techniques are added from different systems such as karate, kickboxing, boxing, wrestling and other styles. Occasionally, old techniques are discarded.
