Kata Jūji-jime (片十字絞) is a chokehold in judo.
[1] It is one of the twelve constriction techniques of Kodokan Judo in the Shime-waza list.
The technique is called a 'half cross strangle' because the palm of one hand of the person applying the choke is facing the person who is applying the choke and the back of other hand is facing the person applying the choke.
Scissoring the hands applies pressure to the carotid arteries reducing blood flow, rapidly resulting in loss of consciousness.
In judo, this technique is always taught under supervision and is similarly closely observed by referees in competition.
