A golf club head having a high COR at its face center and a center of gravity located at a point close to the face and the sole is disclosed herein. In particular, the golf club head comprises a hollow body including a weight lip and face component, and the weight lip extends from the sole inside the body towards the face component without making contact with the face component. The golf club head preferably is a two-piece iron-type golf club head, and each piece is heat treated differently before being welded together to further optimize center of gravity location, ball speed, and COR distribution across the face. |

1. An iron-type golf club head comprising:
a body comprising a top line, a sole, a heel side, a toe side, a frontal opening, and a weight lip; and face cup comprising a striking face, an upper flange with a first length, a lower flange with a second length, and a hinge region where the upper flange and lower flange connect with the striking face, wherein the frontal opening extends completely through the body so that the body comprises a rear opening, wherein the striking face comprises a face center, wherein each of the upper flange and lower flange extends rearwards away from the striking face, wherein the hinge region has a wall thickness of 0.050 inch to 0.065 inch, wherein the first length is less than the second length, wherein the face cup is welded to the body to form a weld line, wherein the upper flange and the top line form a complete top line when the face cup is welded to the body, wherein the complete top line has a width of no less than 0.200 inch and no more than 0.375 inch, wherein the weight lip is disposed proximate the frontal opening, does not comprise any hollow regions, and extends towards the face component, over the weld line, and through the frontal opening without touching any portion of the striking face, wherein the face center has a COR value that is higher than a COR value of any point directly above the face center, and wherein the COR at the face center is at least 0.795. |
