Abstract: A golf club head having an aperture communicating between the face surface for ball striking and a rear of the head. The aperture is configured for cooperative engagement with a flange having a vertically disposed shoulder portion extending from a horizontally disposed base. A front surface of the flange having indicia thereon is viewable in a central portion of the face when the flange is engaged to the head, thereby providing viewable indicia for advertising, targeting the ball, and identifying ownership or a locale visited by the user.

Abstract: A golf putter having a replaceable sole insert for varying putter head weight distribution along the length of the face. The putter has relatively thin face and sole central regions, with much thicker and heavier heel and toe regions. The central region of the sole is cut out. The cut out area has two opposite parallel recessed edges extending away from the back of the putter towards the face. An insert is configure to fit in the cut out area, with edges of the insert engaging the recessed edges to retain the insert in place. The sole may be flat or radiused, and the insert may have a lower surface corresponding to the sole. A neck connects the putter head to a shaft receiving hosel. The hosel has an outer end that is cut at an angle corresponding to the upper surface of the putter.
