An iron-type golf club head comprising a topline, a sole in opposed relation to the topline, and a front portion extending from the topline toward the sole. The front portion includes a leading edge, a substantially planar hitting region including a face center, and a peripheral region. The peripheral region at least partially surrounds the hitting region such that the hitting region and the peripheral region define therebetween a visually-recognizable hitting region boundary line including a sole-proximate boundary line segment such that when the club head is oriented in a reference position relative to a virtual ground plane, and in a virtual vertical plane perpendicular to the hitting region and passing through the face center, the sole-proximate boundary line segment is vertically spaced above the leading edge by a distance D1 that is no less than 2.5 mm.

A golf ball aligning device comprises a shaft having a first and a second end, a handle mounted to the first end and a head member mounted to the second end. The head member further comprises a ball opening extending through the height of the head member having a chamfered or rounded bottom edge to engage a golf ball. An alignment grid on the top face of the head member comprises a crosshair pattern centered with the ball opening. A golf ball engaged with the bottom edge may be manipulated and oriented relative to the alignment grid for setting the trajectory of a shot.

A golf putter includes a putting head including a putting head body, configured with a flat bottom surface, a rear ward angled hose) aperture and a rear angled flat surface; left and right indentations for receiving weights, and left and right detachable wheels attached on sides of the putting head body, such that the putting head is configured to be slidable along a putting surface to enable a golfer to line up the putting head, a golf ball, and a target cup in a front of the golfer, in order to hit the golf ball with a forward sliding motion of the putting head.

Golf club heads include white diffusing top surfaces to aid in club head alignment. Wood type club heads also include a dark diffusing club face so that a crown/face border is emphasized. Scorelines in wood type clubs can be provided with an intermediate contrast surface, and can be displaced from club face center to accommodate player perception when confronted with a white diffusing crown. Putter heads can include dark diffusing alignment lines, and iron-type club heads can include white diffusing surfaces at a sole portion of a club face, at a top line, or a top portion of a club face.

Golf clubs and golf club head structures having an indicator providing a visual indication of a location of a center of gravity of a wood-type golf club are presented. The indicator may include a central portion or hub that is generally aligned with the center of gravity of the club. The indicator may also include a plurality of legs extending outward from the hub toward a perimeter of the golf club head. In some arrangements, the indicator may be formed to distribute a portion of the weight of the club head in order to adjust or move the center of gravity of the club head, in addition to providing a visual indication of the location of the center of gravity.

Embodiments of a co-molded putter-type golf club head comprising a high-density chassis made of a first material and a low-density putter-type body made of a second material. The first material can be a high density metal (i.e., steel or tungsten, but not limited to). The second material can be a low density thermoplastic composite (i.e., polyphenylene sulfide (PPS), polyamide (PA), but not limited to). The chassis comprises a flow aperture, and one or more interlocking features. The putter-type body portion encases the entirety of the at least one interlocking feature. Further, the putter-type body encapsulates the chassis such that the body extends through, and completely fills the flow aperture, to interlock the body and chassis, and thus form the club head. Other embodiments may be described and claimed.

Golf club heads with ribs are described herein. Other embodiments and related methods are also disclosed herein.

A stand-alone putter structured and weight balanced enabling the putter to stand upright in a favorable lie and loft position on a putting surface without any outside support formed of a club head, a shaft connected to the club head, and having a gripping area at the upper end of the shaft. The club head is conventional in design and includes a ball striking face, a rear surface, a heel, a toe, an upper surface and a bottom sole structured to serve as a first ground support surface for the putter in a conventional use position with the bottom sole lying on a putting surface. The club head further includes at least one additional ground engaging support member extending outwardly from the club head forming a second ground support member to maintain the putter in a stand-alone position on the putting surface.

Golf club heads include white diffusing top surfaces to aid in club head alignment. Wood type club heads also include a dark diffusing club face so that a crown/face border is emphasized. Scorelines in wood type clubs can be provided with an intermediate contrast surface, and can be displaced from club face center to accommodate player perception when confronted with a white diffusing crown. Putter heads can include dark diffusing alignment lines, and iron-type club heads can include white diffusing surfaces at a sole portion of a club face, at a top line, or a top portion of a club face.

Embodiments of golf club heads and methods to manufacture such a golf club heads are generally described herein. In some embodiments, the golf club head may include a ball-striking face and a protective aluminum oxide layer coupled to the ball-striking face of the golf club head. The protective aluminum oxide layer is associated with a hardness that is greater than that of the ball-striking face. In further embodiments, golf club heads may include a top portion and at least one of a plurality of interchangeable alignment indicia coupled thereto, which are configured to guide the golf club head relative to a golf ball.
