Re: Really, grab my wrist!
If someone doesn't really grab my wrist, I'll stab or club them. If they do grab my wrist with serious intent, Aikido teaches lot's of mechanically sound ways to make them let go. If they still don't let go, I'll put my weapon in the other hand. If all of this doesn't work, I have a last ditch chance with a throwing technique. If this doesn't work, I got into a fight with the wrong person, I should have had better Aiki.
