●Power Arkla in that located parts to the back of the hand part is adopted by the middle finger, the third finger, finger of little finger. (patent 3919433) bring about power that by hanging tension on big fist part of curve in particular, finger indirect part, grasp back. We suppress the slack in impact and thereby support grip strongly.

●Long belt structure that we adopted immediately in the upper part of wrist further raises concentration of grip.

●We adopt “the nano front desk” of Teijin Ltd. where irregularities of nanosize of the fiber surface produce big frictional force on part that coherence power is necessary in grip of palm. We show big grip power.
