ABSTRACT:
A work holder includes an elongated, hollow, cylindrical handle and a head secured within one end of the handle. A fixed jaw is secured to the head and projects longitudinally from the end of the handle. The fixed jaw has a pointed tip on its free end. A movable jaw is over the fixed jaw and is pivotally seated on an annular flange on the head. The movable jaw has a pointed tip which contacts the tip of the fixed jaw. A spring extends around the two jaws. The spring normally holds the tips together but allows pivoting of the movable jaw to separate the tips and thereby allow insertion or removal of a workpiece.
