I just bought a Musashi Bamboo Katana after reading extensive katana reviews online. This seems like a good, cheap, beginner katana. Now I'm looking for training in tameshigiri, as far as I can tell. I want to learn how to cut with a katana. I'm not ignorant. I know that there is a lot to learn as far as Japanese sword skill...but how/what should I search for to learn how to cut with a katana?
