According to protocol, in Katai (rigid) training, the attacker gets an initial advantage by establishing a strong grip, and there is no attempt to evade the attack. To escape from the attacker's grip a technique must be performed, and performed accurately otherwise it will not affect the attacker.
According to Mel… When an attacker twice your size grips your wrist like a vise, stopping all blood circulation and causing your bones to make cracking sounds, an accurate technique is not what comes to mind…
