The method of this technique is the same as that of the
crescent punch. It is performed with arc-hand and finger
pincers.

Arc-Hand
This is used for attacking the high section of the body only,
and is executed mainly from walking, sitting and X-stances
and occasionally parallel, close and diagonal stances are
used. A reverse strike is normal in the case of a walking
stance.
