Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differ in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.

Golf club heads with a multi-material striking surface

Embodiments of golf clubs with adjustable loft, lie, head mass and methods of manufacturing golf clubs with adjustable loft, lie, and head mass are generally described herein. Other embodiments can be described and claimed.

Golf club head with adjustable fitting mechanisms

Described herein are embodiments of an iron-type golf club head comprising a suspended weight bar within the interior cavity. The weight bar can be attached to and suspended in front of an internal mass pad. The weight bar overhangs at least a portion of the sole and is spaced away from the strike face. The weight bar thereby provides a low and forward center of gravity (CG) position without hindering the flexure of the strike face or the sole.

Iron with mass pad

Golf club head

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, a large Ixy product of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, product of inertia, and aerodynamic drag are also described herein.

Club head having balanced impact and swing performance characteristics

Described herein is a hollow body iron-type golf club head having a sole and ballast configured to relieve stress within a forward portion of the sole. In a first configuration, the golf club head comprises a ballast undercut for relieving stress. In other configurations, the ballast undercut is combined with additional stress relief features, such as a cascading sole near the face sole juncture, for further reductions to face thickness.

Golf club heads with internal undercuts

Embodiments of an iron-type golf club head comprising an L-shaped faceplate configured for flexibility are described herein. The L-shaped faceplate comprises a strike face portion and a sole return that wraps around a leading edge of the golf club head. In some embodiments, the L-shaped faceplate further comprises a top rail extension and a toe extension that extend to the peripheries of the golf club head. The golf club head comprises a rear body configured to receive the L-shaped faceplate to form a hollow interior cavity. The rear body comprises a sole ledge configured to receive the sole return. In some embodiments, the golf club head further comprises a weight pad that overhangs a portion of the sole return. In some embodiments, the golf club head further comprises dynamic lofting features that increase the bending in the rear body.

Golf club head with L-shaped faceplate and dynamic lofting features

Embodiments of a golf club head with an internal lattice structure are described herein. The golf club head can be an iron or putter-type club head. The lattice structure can have varying beam thicknesses that correlate to the effective density profile of the lattice. The effective density of the lattice structure can range between 0 g/mmand 0.0075 g/mm, achieving beneficial product of inertia values for irons and a forward CG location for a putters. For irons, an Ixy product of inertia can be greater than or equal to &#x2212;40 g&#xb7;in. An Ixz product of inertia can be less than or equal to &#x2212;25 g&#xb7;in, resulting in improved sidespin for high and low face impacts. The lattice structure can concentrate mass into a high-toe and a low-heel quadrant or region of the iron to achieve the product of inertia values. Other embodiments may be described and claimed.
