ABSTRACT:
A mechanical cutter for cutting solid materials. It comprises left and right cutting jaws which are moveably connected by a rear hardware unit and rotate about this pivot point. The cutting jaws have opposing curved cutting edges which close but form an opening extending down to the base. The cutting jaws also have central holes. Straps with two mounting holes and an elongated base hole are placed above and below the cutting jaws to guide the linear motion of the cutting jaws. One pair of handle plates is placed above the top strap and another pair of handle plates is placed below the bottom strap. Alternately, a handle assembly is slid over the straps on the right and left side. A circular boss with an eccentric hole is on the end of each top and bottom handle plate. The circular bosses mate with the respective strap mounting holes. The plates are connected with each other through, the eccentric holes in the circular bosses and the central holes in the cutting jaws, by front hardware units. Two handles are each formed by assembly of one bottom plate to one respective top plate. The handles have grips which assist in keeping the handle plates joined. As the handles are separated, the jaws open to allow the material to be cut to enter. As the handles are closed, the cutting edges of the jaws close and cut the inserted material.
