I find George's statement to be true that sword work enhances connectivity. (I would state that it provides a unique training environment in which to learn how to connect and/or disconnect at will.) In fact just about all of our taijutsu is prefaced by sword work or some form of pole arm work. The benefit that weapons work offers non-weapons work is due, I believe, to the decreased tolerances physically, technically and mentally for error allowed within good weapons work.
No question about that.... but I'm sure you will agree... disengaging by "tanking" like that
in a sword encounter is going to leave you at the mercy of the other person... or killed.
Consider also... a person, intent on doing you harm, under the influence of certain mind-altering substances, and not in the least bit concerned about what you might do or try to do to him..... OR even NOT under the influence... as in the Yanagi Ryuken video.
