Field Hand, actually it was Jukado, an American synthesis created by Dr. Bruce Tegner after years of studying in Japan. It was a combination of judo, yawara, savate, karate, jiu-jitsu, and aikido, though most of it was karate and judo. I'm going on 60 and had to give it up many years ago when my sensei moved away. Jukado instructors were not easily found them, probably still aren't.
