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