A method of making a golf club head, comprising:
- providing a golf club head body having a metallic face;
- milling an elongate groove in the face, wherein the groove extends between a heel portion of the body and a toe portion of the body, wherein the groove has a longitudinal axis and the groove is curved so that a length of a maximum depth portion of the groove is shorter than the overall length of the groove;
- pressing a die into the metallic face of the golf club head body to displace material of the face, wherein the die includes a plurality of projections including a plurality of texturing features, and wherein pressing the texturing features into the face forms surface texturing on the metallic face.
A method of making a golf club head, comprising:
- providing a golf club head body having a metallic face;
- milling a plurality of elongate grooves in the face, wherein the grooves extend between a heel portion of the body and a toe portion of the body, wherein the grooves have a longitudinal axis and at least one groove is curved at toe and heel ends about axes of rotation that are perpendicular to the longitudinal axis so that a length of a maximum depth portion of the at least one groove is shorter than the overall length of the groove;
- pressing a die into the metallic face of the golf club head body to displace material of the face, wherein the die includes a plurality of projections including a plurality of texturing features, and wherein pressing the texturing features into the face forms surface texturing between adjacent grooves in the metallic face.
