Re: help on drawing and sheath the sword
I think it is great that you have an interest in learning this particular art. It is both very beautiful and powerful when demonstrated by someone who knows what they are doing. I would strongly recommend not practicing this type of thing on your own. It is very dangerous, even if you are using the typical unsharpened iaito. I've heard a few horror stories from a Iaido Sensei of people dying because they made a mistake and hurt themselves while practicing with no one home to help them. If at all possible find a Sensei to train under. Videos and books aren't the same thing as actually training with other people. You can't attain a true physical understanding and knowledge without experienced critique and correction by a Sensei.
