Abstract: A putter-type golf club head that, when oriented in a reference position, includes a blade portion comprising a striking face, a top line, and a sole, the striking face including a face center. A rear portion of the club head is in communication with, and rearward of, the blade portion. An alignment element of the club head is rearward of, and recessed toward the sole from, the top line, and the alignment element defines a virtual center line segment oriented in a substantially front-to-rear direction at a height equal to about 21.3 mm to about 21.4 mm. The center line segment is not spaced more than 10 mm from a virtual vertical plane passing through the face center and extending generally perpendicular to the striking face, and a width of the club head is no less than 3.0 in.

Abstract: A putter-type golf club head that, when oriented in a reference position, includes a rear portion in communication with, and rearward of, a blade portion and having a rear portion top surface. The club head also includes a projection extending upwardly from the rear portion top surface, the projection having a projection top surface, a heel-ward side surface, a toe-ward side surface, and a rear surface, the projection top surface comprising a generally planar surface. And the club head further includes a sightline formed in the projection top surface and that comprises a groove at least partially filled with a filler material having a visually contrasting appearance to portions of the top surface surrounding the groove, the groove defining a virtual center line segment oriented in a substantially front-to-rear direction at a substantially constant height from a lowermost point of the sole between 16 mm and 26 mm.
