<p>A cutter implement (220), for use within a cutting tool (100) in connection with the securing of a tensioned steel strap about a package wherein a pair of vertically overlapped end portions (12, 14) of the tensioned steel strap are supported upon an anvil (102, 104), is provided with a non-cutting recess portion (224) or notched region (224) at a substantially central portion of its cutting edge (222). With this arrangement, even if the cutting assembly (100) experiences overtravel movements with respect to the anvil (102, 104) while the upper one (12) of the pair of vertically overlapped end portions of the tensioned steel strap is severed by the cutter implement (100), and while the upper surface of the lower one (14) of the pair of vertically overlapped steel straps may be scored by the cutting edge (222) of the cutter implement (220), that portion of the lower one (14) of the pair of straps which is engaged by or disposed opposite the non-cutting recess portion or notched region (224) will remain structurally intact so that the lower one (14) of the vertically overlapped end portions of the tensioned steel strap does not undergo rupture, breakage, or fracture in view of the inherent brittleness of the strap and the tensile stresses incorporated therein. <IMAGE> <IMAGE></p> |
