Claim:
A staple apparatus to staple stacks of paper of different thickness for a stapler having a base with a cavity and a staple opening, a mounting bracket attached to the base, a stapling mechanism with a staple driver guide and a lever with a proximal end and a distal end pivotally mounted on the mounting bracket and the apparatus comprising: an inner base having a top and adapted to be mounted in the cavity in the base; a sliding bracket mounted slidably on the top of the inner base; a cutting anvil mounted on the top of the inner base, adapted to be located below the stapling opening and having a top and two opposite side cutting edges; a cutter mounted on the top of the inner base and the cutter comprising two articulated arms mounted on the top of the inner base, each of the articulated arms having a distal end pivotally connected to the sliding bracket and a proximal end pivotally attached to the top of the inner base; and two bending templates mounted respectively on the articulated arms and aligned with the cuffing anvil, each of the bending templates having a top, a bottom protrusion with a bottom, a top protrusion formed on the top and having a top surface, an inside face and a bending slot defined vertically in the inside face of the top and the bottom protrusions and the top surface of the top protrusion, and the bottom of each of the bottom protrusions being level with the top of the cutting anvil; and a cutter actuator adapted to be mounted on the distal end of the lever; wherein the bottom protrusions of the bending templates are respectively moved by the articulated arms to shear excess length off the pointed legs of the staple by the side cutting edges as the articulated arms approach each other, and the top protrusions of the bending templates bend respectively the uncut pointed legs of the staple.
