  • Patent number: 7124510
    Abstract: A long blade of a knife has first and second working end portions disposed at opposite sides of the blade central portion. The central portion of the blade is pivotally attached to a handle such that, in a first position, the first working end portion is exposed for use and the second working end portion extends along the handle, and in a second position, the second end portion of the blade is exposed for use and the first end portion of the blade extends along the handle. A spring biased locking mechanism is provided to retain the blade in either of the first or second positions.

  • Publication number: 20030213134
    Abstract: The blade of a folding knife has a tang portion by which the blade is pivoted to a handle for swinging between an open position and a closed position. In the open position the blade extends from the handle with its sharpened edge exposed for use, whereas in the closed position the sharpened edge is received in a groove of the handle. A locking link is pivotally mounted on the handle for swinging in the same plane as the blade, with a swinging end of the locking link cooperating with a notch in the tang to automatically lock the blade in the open position. The blade can be released for movement to the closed position by manipulation of buttons exposed at the exterior of the handle, which buttons extend transversely from the swinging end portion of the locking link.

  • Patent number: 6282997
    Abstract: A multipurpose tool having pivoted jaws is provided. Elongated handles are attached to the butt end of each jaw. The handles are channel shaped and define recesses into which the interconnected jaw members can be swung or retracted so as to be nested in the handles. Handle covers are pivoted to each handle and include an opening through which the jaw members pass when moved between the open and closed positions.

  • Patent number: 6070504
    Abstract: Cooperating jaws are pivoted together such that working end portions of the jaw members are movable toward and away from each other. The jaws have butt portions extending opposite the jaw pivot from the working end portions. Such butt portions are, in turn, pivoted to elongated handles for swinging about axes parallel to the axis of the jaw pivot. The handles are channel shaped and define recesses into which the interconnected jaw members can be swung so as to be nested in the handles or, alternatively, into which the interconnected jaw members can be retracted so as to be partially contained within the handles. The handles have forward portions interconnected by a tension spring, and cooperating cam surfaces to bias the handles to predetermined angular positions.

The handles have forward portions interconnected by a link which, in an open position of the handles, is positioned between the handle pivots and the jaw pivot. For a given angle of swing of the handles, the jaws are moved through a smaller angle, i.e., a substantial mechanical advantage is obtained.

  • Patent number: 5957013
    Abstract: Opposing jaw members of a hand tool are interconnected by a first pivot and have working end portions swingable toward and away from each other. The assembly of interconnected jaws is itself pivotally mounted on one or more handles that define a housing for the jaw assembly. The jaw assembly is swingable relative to the housing between a compact, closed position in which the jaws are concealed and an open, extended, working position in which the jaws are exposed. A second handle pivoted to the first handle can be manipulated to effect relative movement of the jaws when the jaws are in the open position.

The assembly of interconnected jaws is itself pivotally mounted on one or more handles that define a housing for the jaw assembly. The jaw assembly is swingable relative to the housing about a second pivot offset from the first pivot, between a compact, closed position in which the jaws are concealed and an open, extended, working position in which the jaws are exposed. A second handle pivoted to the first handle can be manipulated to effect relative movement of the jaws when the jaws are in the open position.
