  • Publication number: 20180243618
    Abstract: A golf club head and a method of manufacturing a golf club head are described herein. The golf club head comprises a club face with a face portion, and grooves positioned on the club face. The grooves each comprise a bottom, a first side wall adjacent the bottom, a second side wall adjacent the bottom, a first top radius adjacent the first side wall, and a second top radius adjacent the second side wall. The club face further comprises a second portion positioned between the face portion, and the first top radius and the second top radius. The second portion of the club face allows for the grooves to appear visually wider to a player, which can provide psychological effects to benefit performance, while still conforming to USGA groove widths standards.
