Abstract
A folding combination tool includes a jaw mechanism with a first jaw piece having a first lug attachment, a second jaw piece having a second lug attachment, and a jaw pivot that joins the first jaw piece and the second jaw piece so that the first jaw piece and the second jaw piece may pivot with respect to each other in a pivot plane. A first handle is pivotably attached to the first lug attachment by a first handle pivot lying perpendicular to the pivot plane, so that the first handle is pivotable about the jaw mechanism in the pivot plane. A second handle is pivotably attached to the second lug attachment by a second handle pivot lying perpendicular to the pivot plane, so that the second handle is pivotable about the jaw mechanism in the pivot plane. A first lug attachment spacing of the first lug attachment from the jaw pivot is greater than a second lug attachment spacing of the second lug attachment from the jaw pivot, so that the handles asymmetrically fold around the jaw mechanism.
