Abstract: A wear-resistant tool insert for machines used in the manufacture of nails, screws, rivets and similar items from a wire starting material. The tool insert is of divided design in the axial direction of the supplied wire. Thus, during application of the tool insert it can "flex" in a controlled manner thereby reducing tensile stress in the tool insert, and reducing the possibility of fracture or breakage of the tool insert, when employed in an overload condition with unacceptably large tensile loads.
