Iron Horseman level 1 - Masters Series Guide to Tekki Shodan Kata and Bunkai

Unfortunately, Tekki Shodan is a much maligned kata in the world of Shotokan Karate. The movements do not look like sparring, and many find it hard to see plausible applications.
Here, however, John Burke, bunkai specialist, shows how the kata is for close-in fighting. An effective form of self defence. Also known as Naihanchi, this is the kata that the renown fighter Motobu Choki based his fighting style on.
