A golf club head to be used for an "iron" that in a preferred embodiment has on its angled face along a bottom edge an arrangement of vertically oriented adjacently located score lines or grooves and above these vertical grooves a non-vertical or slanted arrangement of grooves that in contrast with each other optically provide a modified 90 degree or horizontally oriented visual reference, in the form of a bar-like configuration, which greatly assists the golfer in positioning the golf club head in relation to the intended line of flight of the golf ball. |
