Abstract
Methods of bifurcating the material properties of golf club heads, and wedges in particular, are disclosed herein. The methods of the present invention preserve the bendability and feel of certain parts of the club heads, such as hosel regions, while selectively hardening and increasing the durability of other features, such as scorelines and texturing on the face.
