Claim 0:
1. A plier assembly comprising:
a first handle assembly comprising
a first frame assembly,
a first support block defining a first support block longitudinal axis, a first proximal opening, and a first distal opening,
a first tip assembly supported by the first support block,
a first proximal pin, and
a first distal pin;

a second handle assembly comprising
a second frame assembly,
a second support block defining a second support block longitudinal axis, a second proximal opening, and a second distal opening,
a second tip assembly supported by the second support block,
a second proximal pin, and
a second distal pin; and

a main hinge assembly comprising a main hinge pin for supporting the second handle assembly for movement relative to the first handle assembly; and
a bias assembly a bias assembly arranged between the first and second support blocks and configured to apply a biasing force to the first and second support blocks, the bias assembly comprising
a spring,
a first spring screw to support a first end of the spring relative to the first support block, and
a second spring screw to support a second end of the spring relative to the second support block; wherein

the first proximal pin extends through the second proximal opening to limit movement of the second support block relative to the first frame assembly;
the first distal pin extends through the first distal opening to pivotably support the first support block relative to the first frame assembly;
the second proximal pin extends through the first proximal opening to limit movement of the first support block relative to the second frame assembly;
the second distal pin extends through the second distal opening to pivotably support the second support block relative to the second frame assembly;
the main hinge pin is arranged between the first and second support blocks; and
the first and second proximal openings are sized and dimensioned such that, as the second handle assembly moves relative to the first handle assembly, the first and second support block longitudinal axes are substantially parallel.
