  • Publication number: 20070245570
    Abstract: A hand tool is provided that includes both a fixed implement and a folding or rotatable implement, thereby taking advantage of the security and reliability of a fixed hand tool while also providing an additional implement in order to increase the utility of the resulting hand tool. In order to facilitate use of both fixed and rotatable implements, also provided are a locking mechanism, such as for individually locking the rotatable implement and the handle relative to the fixed implement, and a compound tool that can serve as the rotatable implement in order to mate with and receive at least a portion of the fixed implement, such as in instances in which both the fixed and rotatable implements are deployed.

  • Publication number: 20070204409
    Abstract: A multipurpose folding hand tool including a tool holder permitting exchanges of blades. The tool may include a folding scissors including a spring that is moved into operative engagement with a scissors handle to open the scissors handles apart from each other only as the scissors approaches an extended, operative position with respect to the handle of the folding land tool, within which it may be stowed. A resilient grip member is incorporated in one of the handles of the folding multipurpose hand tool. A wire cutter and a crimping tool are located on pliers jaw tangs, between the pliers pivot and the foldable handles of the tool.

  • Publication number: 20070193037
    Abstract: A scissors-action tool whose blades or jaws are urged apart by a spring and which includes an adjustable member restricting opening movement to a limited blade or jaw separation angle during normal use of the tool, but allowing the blades or jaws to be opened to a wider angle when the adjustable member is moved to a rearward position. The adjustable member may be a rocker including an elongated hole permitting the rocker to be moved rearwardly from a normal position of engagement with a rocker pivot pin.
