Abstract: The present invention can include an apparatus having both a wire nut receiver and a wire insulation stripper thus allowing a user to strip insulation from wires and then connect them using a wire nut with the same apparatus. The apparatus can include a wire nut receiver defining a cavity having a proximal end and a distal end and one or more stripper blades disposed adjacent to the distal end of the cavity of the wire nut receiver. The apparatus can also include a driver, such as for example a hex driver, connected to the wire nut receiver and the one or more stripper blades. Alternatively, the apparatus can be configured such that the diameter of the one or more stripper blades relative to a rotational axis is variable, which in turn allows a user to easily account for different thicknesses or gauges of wire to be stripped.

Abstract: An open end wrench includes first and second jaws. The first jaw includes an arcuate sliding groove having two support walls and an arcuate sliding wall between the support walls. A slide is slideably received in the sliding groove and includes an arcuate sliding face slideable along the sliding wall. Two wings respectively extend from top and bottom faces of the slide. Top and bottom extension faces extend from a wrenching face of the slide and are located on inner faces of the wings. When the open end wrench drives a workpiece to rotate, an outer face of each wing is partially in contact with the second jaw. Force imparted from the workpiece to the wings is transmitted to the second jaw.

Abstract: The present invention relates to the field of open-ended wrenches, and more specifically to a dual pawl assembly which can be used within an open-ended ratchet wrench to facilitate a bi-directional ratcheting motion.

Abstract: A strap wrench includes a strap that is a continuous loop and has notches. No portion of the strap is affixed to any portion of the wrench. The strap is placed around an object that needs to be turned such as an oil filter on an engine. A tension mechanism is then used to tighten the strap into place around the object to be turned. A ratchet mechanism engages one or more notches on the strap to prevent movement of the strap in one direction while allowing movement of the strap in the opposite direction. The combination of the notched continuous loop strap and ratchet mechanism allow the strap wrench to have a ratcheting action after the strap is tightened into place around the object to be turned.
