Torite is the art of seizing limbs and locking joints.
It also covers kyusho - Pressure Points.
In Chinese this system is called Chin Na.
Although it is a subset of Jujutsu, Karate, Kung Fu, Kali, etc, it is also a complete MA system in it's own right if developed to a high enough level.
In class, you may hear me refer to Chin Na or Torite in context, or that we are having a "Chin Na" session.
