Performed by Master Ray Dae Hyun Kwon of OMAC Burlington, after he kindly accepted my request. I shot the video in Spring 2012, and edited accordingly with an ever-important and revealing slow motion portion.
The rythmic music is intentional.
Slow motion starts at 0:50.
This pattern in the OMAC system is based on the official “Tekki Nidan” kata of Shotokan Karate 2nd dan Black Belt.
Performed here by Hirokazu Kanazawa, 10º Dan
Tekki Nidan, Bankai (Application)
