solving the mystery kotogaeshi lock

little fingers catch thumbside of hand
thumb of hand runs across back of uke hand + thumb
between 2 bones of pinky+ring finger of uke
other hand placed on back of uke hand, not fingers
bend hand so uke hand bones go to wrist bones
on opp side
like closing a box
dropping + twisting hip at same time.
keeping uke hand in center

don't twist hip and leave uke hand behind

that's all i remember.
