Abstract
A tool handle includes a handle body having a first end, a second end, an exterior surface and a bore configured to receive a shaft. A wire stripper is integrated into the exterior surface of the handle and configured to cut and remove the insulating layer of a conductive wire. The wire stripper includes a first sharp edge and a second sharp edge intersecting the first sharp edge to form a v-shaped notch.
Claims19
A multi-purpose tool comprising:
- a handle body having a first end, a second end, an exterior surface and a bore configured to receive a shaft along a longitudinal axis, the exterior surface including a channel that is nonintersecting with the longitudinal axis;
- and
- a wire stripper integrated into the exterior surface of the handle and configured to cut and remove the insulating layer of a conductive wire, the wire stripper including
- a first sharp edge;
- a second sharp edge intersecting the first sharp edge to form a v-shaped notch disposed within the channel.

A multi-purpose tool, comprising:
- a handle having a first end, a second end, an exterior surface and a central axis extending from the first end to the second end, the exterior surface including a u-shaped channel that is nonintersecting with the central axis;
- a wire-stripper insert integrated into the exterior surface of the handle and at least partially disposed within the u-shaped channel, the wire stripper insert configured for stripping an insulating layer from a metallic wire;
- a shaft extending from the first end along the axis and coupled to the handle such that a useful torque applied to the handle may be transmitted to the shaft, the shaft including an aperture configured to receive the end portion of a metallic wire in order to form a useful wire loop;
- and
- a bit configured for driving a threaded fastener coupled to a distal end of the shaft.
2 more elements
A multi-purpose tool comprising:
- a handle having a handle axis, a first end at a first axial position, a second end at a second axial position, an exterior surface, and a central cavity extending inwardly along the handle axis from the second end toward the first end, the exterior surface including a non-enclosed channel that is nonintersecting with the handle axis;
- a wire-stripping insert integrated into the exterior surface of the handle and at least partially disposed within the non-enclosed channel, the wire stripper insert configured to penetrate and remove a section of an insulating jacket from a conductive wire;
- and
- a shaft having a shaft axis and comprising:
- a first bore extending along the shaft axis from a first end of the shaft, the first bore having a first hexagonal profile;
- a second bore extending along the shaft axis from a second end of the shaft, the second bore having a second hexagonal profile;
- a coupling section positioned intermediate the first bore and the second bore;
- a first aperture configured for forming a loop in an end portion of a metallic wire, the first aperture positioned intermediate the coupling section and the first end of the shaft;
- and
- a second aperture configured for forming a loop in an end portion of a metallic wire, the second aperture positioned intermediate the coupling section and the second end of the shaft,
- wherein the shaft axis is coaxial with the handle axis when the shaft is coupled to the handle within the central cavity.
