Both in gyakuhanmi; Nage in hidarihanmi; Uke grabs in katatedori.

Slide outside left and put Uke‘s wrist into a nikyo lock, but do not take him down to the ground. Instead, proceed to change the grip to kotegaeshi, but only for a brief moment so you can actually grab the back of Uke‘s fingers with your right hand on your otherwise way to do a kotegaeshi throw.

With the back of his fingers gripped, twist your right hand 180 degrees so Uke‘s palm is now facing outwards, then grab the back of his wrist with your left hand into a normal sankyo grip.

Analysis:

This is henka waza practice to get us used to being able to change grips and techniques several times in the course of one waza. Also, it is pretty neat to take Uke into sankyo without having to do the usual atemi, side step, ikkyo, push forward then go into the sankyo grip.
