Jutte

At the end of Jutte kata, you push the uke into the ground and remove his weapon and so forth.  The final bit is wedging the Jutte between your hip and the opponents neck, unravelling your hand from the Jutte rope and tying up the uke.  The final position is both hands are free to tie the uke up.   This unravelling technique was always awkward so I've made a couple of close up videos of the technique.
