Re: Really, grab my wrist!
The antecedents of aikido and their relationship to weapons styles is an interesting subject, but I think it's a bit of a digression from this discussion of the wrist grab. If the purpose of the wrist grab, as stated above, is to control the "weapon hand"...well, then it kind of matters if there's an actual weapon in it, doesn't it? Nowadays that's much less likely to be the case. So, we're back to the question of what "with intent" means. What's your intention? To stab me with an imaginary knife? Those knives, I'm not so worried about.
