I guess this is a Karate question really, but I stay off the Karate forum now. Can't be doing with the nonsense. So I was hoping for a sensible answer on here. I was recently shown by a friend a demo by the Shotokan master Sensei Kanazawa using a sword. I wasn't aware he studied this. Does anyone know who taught him or where he learnt this? Does anyone know what style it is he does? Unfortunately I don't have a link to the clip I saw because I don't know what site it was on. I think it was just someones website.
