Abstract:
1. A head for a ball striking device, comprising: a face having a ball striking surface located at a front of the head, the face having a plurality of parallel face grooves extending laterally across at least a portion of the ball striking surface; an indicator created on the ball striking surface of the face using a manufacturing technique, located in an area between the face grooves and proximate a lateral center of the ball striking surface, the indicator comprising an indent in the ball striking surface, wherein the indent has a depth that is up to 180 μ-inches, and wherein the depth of the indicator is dimensioned relative to an edge radius of one of the face grooves, such that the indicator is configured to indicate a degree of wear on the ball striking surface when the wear on the ball striking surface reaches the depth of the indicator and causes visual disappearance of the indicator, wherein the indicator comprises a plurality of indents in the ball striking surface, each indent having a depth that is substantially less than a depth of any of the face grooves, and wherein the plurality of indents are arranged along a straight line and are all located between a first face groove and a second face groove of the plurality of face grooves.
