    • An improved face (30) for a golf club head (10) includes shallow (16) and deep markings (13) configured to provide a pleasing appearance when viewed head on, and to frame the central region (18) of the impact face surface (20) of the face (30) when viewed at address. Use of only shallow markings (16) in the central region (18) of the impact surface (20) prevents existence of stress fractures resulting from use of deep markings in the central region (18). This allows for a face thinner than those incorporating conventional grooves in the central regions (18) of their impact surfaces (20), 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 (16) and deep markings (13).
    • 用于高尔夫球杆头(10)的改进的面(30)包括浅的(16)和深的标记(13),其被构造成当从头朝上观察时提供令人满意的外观,并且将冲击面的中心区域(18) (30)的位置(20)。 在冲击表面(20)的中心区域(18)中仅使用浅标记(16)可防止在中心区域(18)中使用深刻痕迹导致的应力断裂的存在。 这允许比在其冲击表面(20)的中心区域(18)中包含常规凹槽的表面更薄的表面,导致优异的抗开裂性和改善的C.O.R. 指定的制造方法特别适用于制造并入这些浅(16)和深标记(13)的球杆。
