Once upon a time I had a beginner with considerable previous training, lets refer to him a MF. After this class he was impressing/frightening the other beginners with a series of jumping spinning crescent kicks. I approached them and told them I had already showed them how to deal with this attack though they didn’t remember it,and asked MF to attack me. He did using his jumping spinning crescent kick where I stepped forward and reached out and touched him. He flew back 20 feet landing in to the wall.
I just flowed a stroke forward and his throat impaled itself onto my fingers. He threw himself away to prevent his own injury. It is important not to thrust into the neck.
I first saw the technique at Sutrisno Sensei’s in several variations back in 1980. Since then I discovered it‘s power. The key is to flow the stroke into the neck. The karate variation to thrust into the neck has a very different potential.
The following example of the technique comes from Shioda Gozo’s ‘Total Aikido The Master Course’ demonstrating Shuchu-Ryoku Focused Power.
