Bone Handle Screw PinThe bone handle is fixed to the shaft by a screw pin that, unlike a thumbscrew, inhibits quick repositioning.
Slots in Bolster SwivelThe swiveling portion, sitting above the bolster body, has slots that allow the claw to be placed quickly in positions of 45 degrees difference.
Claw DetailsThe claw tip consists of two crescent-shaped notches and it has a serrated inner surface.
