Adjustable pliers includes a first plier half, a second plier half coupled to the first plier half, and a stud disposed in a slot of the second plier half. The first plier half includes a first handle and a first working tip opposite the first handle. The second plier half includes a second handle and second working tip opposite the second handle. The slot extends along a path from a first end of the path to a second end of the path, the path extends in a first direction at the first end of the path and extending in a second direction substantially parallel to the first direction at the second end of the path. A performance parameter is defined, at least in part, by a relationship between dimensions of the slot or of the second working tip.

A plier tool for expanding a friction ring having a first opposing end and a second opposing end can include a first arm including a distal portion comprising a first protrusion extending distally from a central axis and a first projection extending outwardly from the first protrusion away from the central axis, the first projection configured to engage the first opposing end of the friction ring; and a second arm including a distal portion comprising a second protrusion extending distally from the central axis and a second projection extending outwardly from the second protrusion away from the central axis, the second projection configured to engage the second opposing end of the friction ring.

A pin assist device that eliminates the need to use a separate tool to insert and/or extract a cotter, or other fastening, pin. The pin assist device allows the user to easily insert or extract a pin in locations that are difficult to reach, in all types of weather and virtually all conditions. Related pin assist devices, hitch pins, and hitch pin assemblies are also disclosed.

A retainer insertion and extraction tool that includes a shaft or handle, a retainer extraction pin at a distal end of the shaft, and a retainer receiving component at a forward end of the shaft. The retainer receiving component includes an annular, generally cylindrical, or cylindrical hammer face mounting, a hammer face, and a retainer capture base that includes a notch configured to receive a magnet and an extending leading edge that, in combination with the notch and magnet, is configured to receive and retain a retainer. The retainer receiving component is configured to insert the retainer into a groove of a bit by applying manual force to hammer face of the hammer face mounting. The retainer extraction pin is configured to remove the retainer from the groove of the bit by applying manual force to the forward end of the shaft, allowing the shaft to pivot against a fulcrum of a base block.
