Due to the sharpened nails of the claw and the active knuckles, the Flying Claw grasps the opponent, and the soft chain is used to pull him back. The general control causes the bearing to have the knuckles bent inward so as to pierce the body. In such circumstances there is little chance for the opponent to escape. If the opponent stays motionless he can endure for a while; otherwise, if he makes efforts to escape, he will be more severely injured. Therefore, the claw is considered as the most tiresome hidden weapon in the field of Kung Fu.
