Whitestar: Jukado is Bruce Tegner's attempt to have a system of belt rankings/motivation for those who did not want to study any of the non essentials of self-defense, The techniques are the same as in any system of effective s/d, I saw in another post you were looking for an effective s/d system, Jukado will qualify, as does ww2 hand to hand, The main difference is jukado emphasis's the lower level of attacks, non violent and violent, how to stop and control your attacker, What I would like to say is what most people are likely to face, while HTH emphases the more deadly types of attackers, where you are justified in killing or just totally messing up your attacker. Among the best in HTH is Carl Cestari, Mr Cestari has tapes available on battlefield forum.
