My favorite moment of this clip may seem a little mundane. Master Shinjo is impressive throughout, as always, but it's the front snap kick before the knee strike. There's something about a perfectly-executed Uechi toe-kick seen from the side like this. So few people I see exhibit that perfect, deeply-penetrating directional force. So often there is at least a little bit of residual "swing" from the lower leg rotating as the knee is extended, something I am also guilty of, I am sure. As I recall, master Kanei Uechi had a similar-looking front kick. Both remind me of what a horse accomplishes with their natural back kick--the weapon (whether it be foot or hoof) is hurled in a straight line at the target.
