Assignee:

Acushnet Company - Fairhaven MA

International Classification:

A63B 53/04

Abstract:

A golf club head with improved striking face performance is disclosed herein. More specifically, a golf club head includes a striking face with a thickened central region surrounded by transition region that reduces radially in thickness as it extends away from the central region is disclosed. The striking face geometry results in more uniform characteristic time measurements across a large percentage thereof.
