Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein. The lattice can comprise a plurality of flexure shapes that facilitate in faceplate bending. The flexure shapes of the lattice can comprise a reentrant, concave, or non-convex shape. The lattice can comprise at least one repeating pattern of flexure shapes that can be interconnected or spaced apart. During golf ball impacts, the flexure shapes flex to store energy through linear and torsional bending.

A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

A golf club is disclosed that has a golf club head with a face having peaks or ridges and deep grooves or valleys. The deep grooves or valleys promote improved “feel” and/or reduced “smash factor” which may be particularly desirable when the golf club head comprises a putter face. The deep grooves or valleys may eliminate the need for costly soft metal alloy faces and/or polymeric or other resilient inserts between the face and the body of the golf club head.

A method of measuring and recording at least one performance variable of a golf club head.

A wood-style golf club head includes a strike face and a body that cooperate to define a hollow internal club head volume. The strike face formed from a strike plate having an outer perimeter and a frame surrounding the strike plate. The strike plate is affixed to the frame across the entire outer perimeter. The strike plate and frame define a continuous ball striking surface that has a surface texture characteristic of milling that extends continuously across both the strike plate and the frame.

Some embodiments include club heads having reinforced club head faces. In one example, the club head comprises a variable face thickness profile with thickened and thinned regions. The face includes a thinned perimeter region positioned near a perimeter of the face, and a thickened central region positioned over a geometric center of the face. The club head further comprises a 360 undercut that extends along the entire perimeter of the face. The club head further comprises one or more reinforcement ribs to improve the frequency response during golf ball impacts. The combination of the thinned perimeter region, thickened central region, and 360 undercut reinforces the club head while permitting the face to bend. Other embodiments of related club heads and methods are also disclosed.

Some embodiments include a first golf club head and a second golf club head. The first golf club head includes a body having a face portion, and the second golf club head includes a body having a face portion. Meanwhile, the first club face portion comprises a face surface and at least one first club groove, and the second club face portion comprises a face surface and at least one second club groove. An edge radius of the first club head groove(s) can be less than an edge radius of the second club head groove(s), a base width of the first club head groove(s) can be less than a base width of the second club head groove(s), and/or a sidewall angle of the first club head groove(s) can be greater than a sidewall angle of the second club head groove(s). Other embodiments of related club heads and methods are also disclosed.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a method of manufacturing a golf club head includes forming a body portion with an interior cavity, forming a face portion, attaching the face portion to the body portion to close the interior cavity, injecting a polymer material into the interior cavity from a port on the body portion, and inserting a first mass portion into the port to close the port. The method further includes attaching a second mass portion to the body portion below a horizontal midplane of the body portion. Other examples and embodiments may be described and claimed.

An iron golf club head comprises; a head main body including a club face provided with score lines; a weight member having a specific gravity larger than that of the head main body; and a fixing member having a specific gravity larger than that of the head main body and less than that of the weight member, and fixed to the head main body by welding so as to cover the weight member. In a forward tilting state of the club head in which the score lines are horizontal and the club face is vertical, the distance D in the perpendicular direction to the club face from the backmost position of the club head to the center of gravity of the weight member is not more than 47.3% of the maximum thickness w of the club head which is the shortest distance from the backmost position of the club head to the club face.

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.
