Carter Hargrave founded the combat martial art known as American Combat Kempo. At the same time he wrote the Japanese Kempo Karate Manual that detailed his new combat street fighting system. He then organized the World Kempo Association to offer his new fighting art to other Kempo and Kenpo systems who are more focused on the tournament aspects of the art, but were needed some hard fighting moves to add to their systems so their members could meet a street attack.  

American Combat Kempo was just what the other arts needed, and Hargrave's World Kempo Association was there to assist them in whatever capacity the student or school needs.
American Combat Kempo is primarily developed from heavily modified Okinawan Karate, Ju Jitsu, and Okinawan Weapons. While the end result is so off base from its traditional limited origins, the final arts beauty is in its direct and modern applications. Weapons of old are used for defense as well as the other side of the coin, modern edged weapons and firearms.

In the Japanese Kempo Training Manual that Hargrave wrote lists his rules of combat which have nothing to do with fighting fair. The Kempo style also utilizes standard sparring to interact with other arts but Hargrave admits his standard fighting method is so severe that the sessions will be over in ten to twenty seconds.

“I have never had a student loose a real fight on the street, and there have been plenty due to some of the hazardous professions my students engage in. In the end if my legacy is that I helped keep honorable people safe from the bad guys, Im good with that” says Hargrave.
