The claw tips are tapered and pointed, enabling the claw to dig under nail heads that are below the wood surface. The claw has a very sharp V slot near the end of the claw. The head is provided with a cup in the pocket which is used to hold a nail head when one handed spiking with a nail positioned with the head of the nail in the cup and a shank in the slot captured by the V shape of the slot. The neck is a long reach neck with a progressive radius and the face is oversized and slightly contoured to about equal to a 6" R. The edge of the face is chamfered.
