This video shows bunkai for the opening sequence of Tekki Sandan / Naihanchi Sandan kata. The video also shows how the discrete motions can be combined together into a single drill.
I am of the view that the Nidan and Sandan versions show alternative expressions of the core principles of Naihanchi Shodan (the original stand-alone kata once simply known as “Naihanchi”). Here we see variations on the limb-control and trapping methods that are first introduced in Naihanchi Shodan / Tekki Shodan.
Thanks for your support of these videos!
All the best,
