Grandmaster “Iron” Kim

The 8th Generation Grandmaster of the Oom Yung Line of Martial Arts

Grandmaster "Iron" KimAt the age of seven, Grandmaster “Iron” Kim began his life’s path in the study and practice of martial arts. To achieve perfection of his martial arts movements, Grandmaster “Iron” Kim many times chose the solitude of the mountain and ocean areas of Asia to practice the forms and techniques that he learned. Although he learned from many qualified teachers, a majority of the knowledge that Grandmaster “Iron” Kim possesses was passed down through Grandmaster Wang Po, the 7th generation Grandmaster of Yin Yang Doe.

Champion of All Asia

In 1956, Grandmaster “Iron” Kim competed in and won the All Asia Championship that was sponsored by Grandmaster Wang Po and was held in the Cho Leung area of Pusan. The Chinese title of Chung Moo Jik or “champion” was bestowed upon Grandmaster “Iron” Kim. The first place award that he received was called a Chung Moon Chung. A Chung Moon Chung is a paper scroll with wooden rods at each end. It is inscribed with the accomplishments of the winner and carries the official seal of the tournament. Several prominent judges and martial artists were in attendance at this championship and they hold in their memory the truth of this occasion.

The presiding judges were Yang Chou Fai (then a resident of Taegu), Wang Sei Kau (then a resident of Pusan) and Hwan Byung Quan (then a resident of Pusan). These three judges were originally residents of China. Also in attendance were Mok Jing Quan, from Osan, Korea; Chae Jung Su, of Dong Nae, Pusan; Park Hyun Su, of Sum Yun, Pusan; Yu Gee Han, of Taegu; Chil Sung and Park Yung-Gil of Daichon, Korea. Those knowledge of martial arts during that period will recognize the tradition of the Chung Dong Yang Moo Sul Yun Moo Dae Hwa (All Asia Championship Tournament) and the names that appear above.

After winning the All Asia Championship Tournament, Grandmaster “Iron” Kim continued to excel in martial arts form and movement. He was teaching others and, in fact, sponsored many of the Chun Dong Yang Moo Sul Yun Moo Dae Hwa championships, which at the time were held in the Sum Yun area of Pusan, Korea. Other cosponsors of these tournaments with Grandmaster “Iron” Kim were Park-Yang Su, Choe Jung Su, Sun Baek Yew and Ee Jun Yu, all having the accomplished position of Chong Sa Bu or Sa Bu (Assistant master or one step below) in their respective styles. The strength of the Oom Yung line that Grandmaster “Iron” Kim demonstrated at these contests convinced other practitioners to decline to challenge him in the years that he sponsored the tournament. Because he was uncontested champion during that time, Grandmaster “Iron” Kim was bestowed the honorable and respected position and title of “Chon Shim Pan Whey Won Chaeng,” or “Supreme Judge and Arbiter” by the co-sponsors and the martial arts experts who participated in these tournaments. Even though Grandmaster “Iron” Kim earn the title of uncontested Champion of All Asia, he felt that there was much more to learn and thus he continued to study and develop his skills further. His ultimate hope was that all martial arts could some day be united.

All Martial Arts United

Grandmaster "Iron" KimIn the early 1960’s Grandmaster “Iron” Kim expanded his quest for knowledge. He traveled and sought Masters who had reached a higher level of Moo Doe (traditional martial arts) knowledge. There were seven top practitioners from an elite group of about twenty Masters throughout East Asia with whom Grandmaster “Iron” Kim exchanged individual skills in the martial arts. All the names of the practitioners that appear above were part of that group of about twenty top Masters. Grandmaster “Iron” Kim’s purpose was to build his own wisdom, knowledge and understanding in the Moo Doe traditions of the eight main styles. Regardless of how far he had to travel or the difficulty of training, Grandmaster “Iron” Kim relentlessly pursued, learned and absorbed the complete knowledge of form and movement from these top practitioners. After completing the training, Grandmaster “Iron” Kim then shared his knowledge of the Oom Yung / Chung Moo style with the top members from this group. After seven years of training and sharing his knowledge with the best practitioners in East Asia, Grandmaster “Iron” Kim became one of a few elite practitioners who were well rounded in the eight main martial art styles. He was one of a few Moo Doe practitioners capable of uniting all Moo Doe and qualified to teach eight martial arts together as one style or “All Martial Arts United”. Finally, after seven years, his wish that the Oom Yung line could become “All Martial Arts United” became a reality.

Of the hundreds of millions of people who practice martial arts in the 20th century, Grandmaster “Iron” Kim is one of fewer than 10 practitioners that has achieved unprecedented fame and recognition for being the most skilled in Moo Doe.


Grandmaster “Iron” Kim’s goal was to teach the Oom Yung /Chung Moo line to people of all nations, and to do that chose to build a strong foundation of martial arts in the United States from which to spread worldwide. With this goal, Grandmaster “Iron” Kim left Asia and came to the United States in the early 1970’s.

In 1972 Grandmaster “Iron” Kim demonstrated the discipline and strength of Oom Yung Doe by  executing a successful jump from the top of a building eleven stories in height, a form called Kyong Gong Sul Bope. Very few individuals have ever accomplished such a feat. Between 1973 and 1979, after educating himself about the American way of life, Grandmaster “Iron” Kim opened the first of four schools in the United States.

In early 1975, Grandmaster “Iron” Kim briefly returned to Korea. It was at this time that Grandmaster Wang Po, the 7th generation Grandmaster of Yin Yang Doe, passed to Grandmaster “Iron” Kim the remaining knowledge and traditions that he possessed. Soon thereafter, the title of 8th generation Master of the Oom Yung line was bestowed upon Grandmaster “Iron” Kim. Grandmaster Wang Po passed away in 1976 in Pusan at the age of 93.

As the number of practitioners and schools has grown, Grandmaster “Iron” Kim shared much of his knowledge and skills with a team of master level instructors who now direct the training across the country. Grandmaster now focuses much of his attention to the study of improving the physical and mental abilities of all age groups, with special emphasis on the aging.
