Ashi-Hishigi also called an Achilles lock or simply an ankle lock, is a technique described in both The Canon Of Judo[1] by Kyuzo Mifune and Brazilian Jiu-Jitsu, Theory and Technique[2] by Renzo Gracie and Royler Gracie as well as demonstrated in the video, The Essence Of Judo. It is classified as a joint lock (Kansetsu-waza), and is not a recognized technique of the Kodokan. However, it is a commonly used technique in both Brazilian Jiu-Jitsu tournaments and Mixed martial arts competition.

Technique Description[edit]

Executing this lock involves pressing the achilles tendon into the back of the ankle or lower leg. It is typically performed by wedging a forearm, especially a bony part of it, into the Achilles tendon. Simultaneously leveraging the foot and the leg over the forearm, which serves as a fulcrum. This causes severe pressure on the Achilles tendon, often resulting in an ankle lock, since the ankle is being used as a point of leverage. Similarly, some ankle locks also cause a compression lock on the Achilles tendon, and hence the term "Achilles lock" is often also used to describe such ankle locks.
