13. The tool collet of claim 3 wherein the insert disposed within a recess in the opening surface is an elongated, resilient, gripping member disposed within the recess and extending a predefined distance away from the opening surface and into the through opening.
14. In combination, a hand tool and a tool collet for creating a lanyard attachment point on the hand tool, the combination comprising:
a hand tool having an elongated body that extends to a first hand tool end wherein the elongated body has a predefined cross-sectional diameter that is equal to or larger than a cross-sectional diameter of the first hand tool end; and
a tool collet attached to the elongated body of the hand tool, the tool collet comprising:
a collet body having a first body side, a second body side, a peripheral body surface between the first body side and the second body side, a collet through opening with an opening surface, the collet through opening extending through the collet body transversely from the first body side to the second body side. and an annular groove in one of the first body side, the second body side or the peripheral body surface of the collet body, the collet body being divided radially relative to the collet through opening and defining a first body component and a second body component fixedly attached to the first body component and wherein the through opening is formed by the first body component and the second body component, the through opening surrounding and securely attached to the elongated body of the hand tool;
a lanyard ring having an annular end adapted to be disposed and captured within the annular groove wherein the lanyard ring is adapted to freely slide along the annular groove; and
one or more fastening members that extends between the first body component and the second body component wherein the one or more fastening members are adapted to securely fix the first body component to the second body component.
15. The combination of claim 14 further comprising a gripping member disposed within the collet through opening between the opening surface and the elongated body of the hand tool.
16. The combination of claim 14 further comprising a tool lanyard removably attached to the lanyard ring.
17. A tool collet kit for a creating a lanyard attachment point on a hand tool, the kit comprising:
a collet body having a first body side, a second body side, a peripheral body surface between the first body side and the second body side, a collet through opening with an opening surface the collet through opening extending through the collet body transversely from the first body side to the second body side, and an annular groove in one of the first body side, the second body side or the peripheral body surface of the collet body, the collet body being divided radially relative to the collet through opening and defining a first body component and a second body component adapted to be fixedly attached to the first body component and wherein the through opening is formed when the first body component and the second body component are attached to each other;
