Uchinadi DVD 1: Original Karate of Okinawa by Toshishiro Oshiro
The author explains and demonstrates how to knock down an opponent by simply touching his body, by using the power of "atifa." This program includes demonstrations of the original techniques of karate, katas Pinan 1-5 and Naihanchi, and of course those amazing striking and blocking techniques.
Bought it elsewhere in videotape, but you got to get this on on DVD. Oshiro captivates you with his Koryu (true ancient way) of performing these katas which have since lost their "umf" in modern systems.
