ABSTRACT:
The planar knife blade extends rearwardly from the hollow base of the needle assembly. The base is designed to be received in the cylindrical opening of the body of a fastener attacher. The end of the opening is partially obstructed by a protruding shoulder. The blade is tangentially aligned with the bore. It extends from a point proximate the side surface of the base through a plane bisecting the base to a point a short distance beyond the plane, so as to accommodate the shoulder. Accordingly, the assembly can be used in fastener attachers either adapted to receive a knifeless needle or a needle with a knife blade mounted within the base.
