First of all, I'm glad to finally join you guys on this great forum. Formalities out of the way, I would like to ask your guys' expertise on the matter combining arts and swords. Familiar with kenjutsu, I encounter tojutsu mentioned here and there in articles, and only referred to as a very general term for sword techniques. However, doesn't "to" refer precisely to single-edged swords, while "ken" to double-edged? Therefore, isn't there a confusion going on in the way we call sword arts, for ex. what we know as kenjutsu would correctly be tojutsu, since all the blade types it deals with are single-edged?
