Jujitsu: Toward One Technique Book by George Kirby

In Jujitsu: Toward One Technique, author George Kirby, a 10th-degree black belt, presents effective ways a student of any martial art can apply that art to the realities of the street. There's a difference between being able to do a beautiful form and actually using that knowledge in real-life situations. Self-defense requires movements that are extremely effective in their simplicity. However, acquiring that "simplicity" takes patience and practice.
