  • Fixed-blade knife with pivotable side pieces
    Publication number: 20060080841
    Abstract: A fixed-blade knife includes a unitary blade having an implement, a tang, and a pivot region between the implement and the tang. The unitary blade is disposed between a pair of parallel and spaced-apart side pieces that pivot to cover or expose the implement. In the pivoted position wherein the implement is exposed, the side pieces form part of the handle that is used to grasp the knife. A locking structure locks the side pieces in a selectable position, and a limit structure prevents overrotation of the side pieces.
