| 20100009773 | Method for making a golf club face - An improved face for a golf club head includes shallow and deep markings configured to provide a pleasing appearance when viewed head on, and to frame the central region of the impact surface of the face when viewed at address. Use of only shallow markings in the central region of the impact surface prevents existence of stress fractures resulting from use of deep markings in the central region. This allows for a face thinner than those incorporating conventional grooves in the central regions of their impact surfaces, resulting in both superior resistance to cracking and improved C.O.R. Specified methods of manufacture are particularly suited for making clubs incorporating these shallow and deep markings. | 01-14-2010 |
