The late Seigo Yamaguchi and some of his students like Sekiya, Tissier, Inaba, Gleason, etc, have a background in Kashima Shin Ryu kenjutsu rather than the more common Iwama style sword. It helps give their aikido a very different flavor.
I would say the same with Tetsutaka Sugawara shihan who has a background in Iwama weapons (as a deshi) and teaching qualification in Katori Shinto Ryu.
We hosted him in our dojo last December; his aikido indeed has a different flavor. We hope to host him again in 2008. If any of your "KLiens" are interested, please do PM me.
