Iaijutsu_Tachi Uchi no Kata - Kono Hyakuren Hanshi 

You are welcome, it is the only one I know of this poorly known set created by Oe Masamichi Sensei.

@@MokuraiDojo it's nice to see a "practical application" of some seiza no bu Waza. I especially liked Uke Nagashi.

@@gomcse Tachi Uchi no Kata was developed by Oe Masamichi Sensei to teach to Middle school children. It puts more emphasis on distance than timing. I did not use to like this set of katachi, but little by little I am beginning to appreciate them as an excellent teaching set for beginners. This version of Ukenagashi, as you very well point it out, is very close to the Seiza no bu version. My late Master Masayuki Shimabukuro Hanshi taught it to us as "Ukenagashi sono Ni", a variation of Ukenagashi of the Tachiuchi no Kurai set. 3 or 4 years ago, my present Master Carl Long Hanshi, started to teach it to us as a part of Tachi Uchi no Kata

@@MokuraiDojo I am familiar with Shimabukuro Hanshi, and had the pleasure of speaking with Long Hanshi 3 years ago over the phone. I have their full collection of videos and books. I have been studying for over three years with Minobu Miki sensei, direct student of Iwata Norikazu Sensei. It's very nice to talk to you.

@@gomcse We are lucky to have known such great masters. I put these videos together for my students mostly, but it has taught me a lot also !

I would not bet my head on it, but is is likely. Kono Hyakuren was the 20th headmaster of what was considered the main line of Muso Jikiden Eishin Ryu before his death. That makes it very likely that he used shinken on a regular basis.
