He practised the whole range of Aiki-ken in his Ryushinkan Dojo in London. I was his partner at a demonstration held in London, with Chiba Shihan present. It was Chiba S who put a stop to M Sekiya's kesa-giri training in aikido classes. The only thing MKS did not teach was the paired 31 jo kata.
That is very interesting indeed, and I hadn't heard this story. I was under the impression that Chiba Sensei had encouraged Kanetsuka Sensei to study kesagiri.
