wherein at least one groove is oriented on the striking face, extending between the heel and the toe;
a first groove enhancement area oriented on the striking face, surrounding the at least one groove;
wherein the first groove enhancement area has a second surface finish that is different from the first surface finish, the golf club head further comprising;
a second groove adjacent to the at least one groove, wherein the at least one groove and the second groove form a plurality of grooves;
a second groove enhancement area oriented on the striking face, surrounding the second groove, wherein the second groove enhancement area has the second surface finish that is different from the first surface finish;
wherein the first groove enhancement area surrounding the at least one groove and the second groove enhancement area surrounding the second groove are adjacent to one another;

Abstract
Golf club heads with enlarged grooves, wherein a portion of the finish adjacent or within the groove is removed to create the visual appearance of enlarged grooves. The surface finish of the groove enhancement area surrounding the groove is matched to be the same as the surface finish of the groove, preferably a bright, smooth or shiny metallic finish. This surface finish of the remainder of the striking face of the golf club is a second surface finish, preferably a dark or black matte, or rough finish. The contrast between the two finishes gives the perception that the grooves are larger than they are physically.
