This is the bok that shows what the Bassai Sho Shotokan Karate kata does. It takes movemnts that many show as preposterous for the sake of self defence and applies them to modern situations and needs. Sensei John Burke teaches internationally on courses and seminars, and has produced a series of books and dvds that explain what Karate can really be used for. Forget the fads, Tradition is where it's at.
