  • Publication number: 20260061472
    Abstract: A bending tool for bending tubing, the bending tool includes first and second bend bodies that respectively include first and second arcuate channels. A central channel is cooperatively formed between the first and second bend bodies, and tubing partially disposed in the central channel may be bent around either of the first or second bend bodies to impart a desired bend. An attachment may be provided on the bending tool for releasably coupling the bending tool to another tool.

  • Publication number: 20260001204
    Abstract: A tool includes first and second halves pivotally coupled together at a pivot and having respective first and second jaw portions with respective first and second front faces. The first and second jaw portions have respective first and second contact surfaces disposed proximal to the front faces, and when the first and second contact surfaces are brought together, they cooperatively define a contact plane that extends along a longitudinal axis of the tool. The jaw portions respectively include first and second relief regions having a depth from the contact plane and respective first and second grooves disposed in the relief regions, wherein the first and second grooves are offset by an offset distance.

  • Publication number: 20250262721
    Abstract: A multi-function tool that is adapted to cut various materials and has multiple features. The tool includes first and second halves pivotally coupled together at a pivot and respective first and second jaw portions. A first cutting section is cooperatively formed by first and second cutting edges respectively disposed on the first and second jaw portions, and a second cutting section is cooperatively formed third and fourth cutting edges respectively disposed on the first and second jaw portions. A grip feature and/or a wire stripping feature may also be defined by a grooves or indents disposed on the first or second jaw portions between the first and second cutting portions.

  • Patent number: 11691249
    Abstract: A push button release mechanism for coupling together two portions of a tool, such as pliers. The push button release mechanism can include a push button and one or more balls pushed in a radially-outward direction by geometry of the push button to pivotally couple the two portions together. The balls are normally pushed outward by an engagement portion. Depressing a push button head axially downward causes the balls to align with a receiving portion, which allows the balls to descend into the interior of the mechanism. The push button release mechanism is also threadably coupled with a threaded opening of one of the portions. The threaded opening can have deformed threads to increase the retention torque required to rotate the push button release mechanism.

  • Publication number: 20200061778
    Abstract: Disclosed are adjustable pliers where the pawl mechanism can be engaged or disengaged to adjust a jaw gap of the pliers. The pawl mechanism can be disengaged either by rotating the handles so as to cause a tab to engage a pocket, and/or by lifting upward on the handles to disengage the pawl teeth from corresponding teeth in a slot of one of the handles. The pliers are therefore advantageous because they do not require a button or lever to adjust the jaw gap, and can therefore be adjusted easily.
