Die assembly comprises a die plate having one or more die inserts therein. The die plate has a recess within which the insert is positioned. The die opening in the insert extends normally of the oppositely directed major surfaces of the insert so that the insert can be reversed. The original obverse surface of the insert thus becomes the reverse surface and the original reverse surface becomes the obverse surface. The necessity of sharpening the die insert in the conventional manner is thus eliminated. Also disclosed is an improved system for mounting die inserts in a die assembly.
