Professor Wally Jay introduces his unique Small-Circle Jujitsu Self Defense Technique in this new series of DVDs. Volume 5: Effective Finger Locking Techniques discusses the principles of learning these highly effective techniques for self-defense application. Finger locking techniques can cause pain without causing injury to the assailant, making it a practical method of self defense. Professor Wally Jay is a Black Belt Hall of Fame member (1969), 10th dan in jujitsu under Juan Gomez (a top disciple of Henry S. Okazaki) and a sixth dan in judo under Ken Kawachi. Jay is one of the few martial artists this century to have come up with a theory of fighting, developed it and put it into practice. His influence is felt throughout the martial arts industry.
