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.
