Aspects of the invention are directed to golf club having a crown, a sole, a face, and a primary alignment feature hard tooled into the golf club head. In some embodiments the golf club has a primary alignment feature comprising a line delineating a transition between at least a portion of the crown having an area of contrasting shade or color with a shade or color of the face. The primary alignment feature is hard tooled into the golf club head with the face of the golf club body.

A cast cup can include a forward portion of a golf club head, including a hosel, forward portions of a crown, sole, heel, and toe, and a face portion or an opening to receive a face insert. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a rigid club head body, such that the club head body defines a hollow interior region, a crown opening, a sole opening, and/or face opening. The cast cup and rear ring can be made of different materials, including various metals, composites, and polymers. Composite crown, sole, and/or face inserts can be coupled to the crown, sole, and/or face openings. Weights can be coupled to the cast cup and to the rear ring. The face can have a complex variable thickness geometry.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, a bottom portion, a face portion, and a periphery. The bottom portion may include a forward portion and a rear protrusion at or proximate the rear portion. The rear protrusion may project downward from the periphery and extend longitudinally in a rear-to-front direction. The rear protrusion may include a front-side portion. A toe-side portion may extend rearwardly from the front-side portion towards the rear portion. The rear protrusion may also include a heel-side portion extending rearwardly from the front-side portion towards the rear portion. A weight port may be defined by the rear protrusion. Other examples and embodiments may be described and claimed.

Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The insert can further comprise multiple materials to improve sound and feel. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The lower portion can have a depth greater that the upper portion depth. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.

A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A non-metallic striking surface is positioned at the forward portion of the body.

Disclosed herein is a golf club head that comprises a body. The body comprises a sole portion, a crown portion, a skirt portion, and a face portion, positioned at a forward region of the golf club head, opposite a rearward region of the golf club head, and extending from a toe region to a heel region of the golf club head. At least a portion of the body is made of a titanium alloy. The golf club head also comprises a large weight, coupled to the sole portion of the body and made of a steel alloy. A mass of the large weight is at least 40% of a mass of the portion of the body made of the titanium alloy. A total mass of the large weight and the portion of the body made of the titanium alloy is at least 210 grams.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a body portion having a center cavity portion, a toe-side cavity portion, a heel-side cavity portion, a first port on the body portion connected to the toe-side cavity portion, a second port on the body portion connected to the heel-side cavity portion, a first filler material in the center cavity portion, and a second filler material in the toe-side cavity portion and the heel-side cavity portion. The toe-side cavity portion is at least partially filled with the second filler material from the first port or the second port, and heel-side cavity portion is at least partially filled with the second filler material from the first port or second port. Other examples and embodiments may be described and claimed.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion including a face portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. An inner side of the face portion may have a center portion, an outer wall portion at least partially surrounding the center portion, and a plurality of inner wall portions connecting the center portion to the outer wall portion. Other examples and embodiments may be described and claimed.

A golf club head includes a club body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. The golf club head also includes an adjustable weighting system positioned on the club body, the adjustable weighting system includes a single channel and a member that is received by the single channel and fastened to the club body, where a plurality of weights are coupled to the member. The golf club head can additionally or alternatively include a face angle adjustment system positioned on the sole, the face angle adjustment system includes a member that is removably received by the single channel and fastened to the sole, the member includes a first end member and a second end member, wherein the member is configured to be repositioned within the channel to adjust a resting face angle of the golf club head.

Golf club heads are described having a club head portion, a shaft portion connected to the club head portion, and a grip portion connected to the shaft portion. The club head portion has a heel portion, a sole portion, a toe portion, a crown portion, a hosel portion, and a striking face. The striking face can have a center face roll contour, a toe side roll contour, a heel side roll contour, a center face bulge contour, a crown side bulge contour, and a sole side bulge contour. The toe side roll contour can be more lofted than the center face roll contour. The heel side roll contour can be less lofted than the center face roll contour. The crown side bulge contour can be more open than the center face bulge contour, and the sole side bulge contour can be more closed than the center face bulge contour.
