Claim 8:
9. A method of installing and removing retaining rings comprising the steps of:
providing 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;

providing 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 extending through the second proximal opening to limit movement of the second support block relative to the second frame assembly, and
a second distal pin extending through the second distal opening to pivotably support the second support block relative to the second frame assembly;

extending the first proximal pin through the second proximal opening to limit movement of the second support block relative to the first frame assembly;
extending the first distal pin through the first distal opening to pivotably support the first support block relative to the first frame assembly;
extending the second proximal pin through the first proximal opening to limit movement of the first support block relative to the second frame assembly;
extending the second distal pin through the second distal opening to pivotably support the second support block relative to the second frame assembly;
providing a main hinge assembly comprising a main hinge pin;
arranging the main hinge pin between the first and second support blocks to support the second handle assembly for movement relative to the first handle assembly;
sizing and dimensioning the first and second proximal openings 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; and
arranging a bias assembly between the first and second support blocks to apply a biasing force to the first and second support blocks, where the step of arranging the bias assembly comprises the steps of
providing a spring,
arranging a first spring screw to support a first end of the spring relative to the first support block, and
arranging a second spring screw to support a second end of the spring relative to the second support block.
