Re: Regrading grabs in Aikido...
Grabbing both hands from the rear is a kind of throw. O`Sensei does it in one of the films from AikiNews. Also, it is shown as a technique in a Daito Ryu book I have. You pull both hands to the rear, off balance the guy, bring both hands to the ground, step on them leaving your hands free to pull out a knife and cut the throat. At least that`s how it`s shown in the book!
