Golf club head

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

An iron-type golf club head with a cavity formed via a multi-stage forging process. The forged iron-type golf club head is formed from a single billet of material. An intermediate step of the multi-stage forging process creates a cavity in the iron-type golf club head which can receive an insert. The resultant iron-type golf club head has a substantially lower center of gravity and higher moment of inertia when compared to a traditionally forged iron-type golf club head lacking a cavity. Additionally, the resultant iron-type golf club head has a more solid feel than a traditionally cast iron-type golf club head as a result of the tighter grain structure the forging process yields.

Forged golf club head

Embodiments of an iron-type golf club head comprising a high moment of inertia and a damping system. The damping system includes an insert covering a lower portion of the back face and a badge covering an upper portion of the back face. The damping system covers a large proportion of the back face and provides a club head with desirable sound and feel characteristics.
