Embodiments of golf club heads and methods to manufacture golf club heads may include a golf club head having a body portion, a first mass portion, and a second mass portion. The first mass portion has a first mass portion first end and a first mass portion second end such that a distance between the first mass portion first end and the first mass portion second end defines a first mass portion dimension. The second mass portion includes a second mass portion first end and a second mass portion second end such that a distance between the second mass portion first end and the second mass portion second end defines a second mass portion dimension. The second mass portion dimension may be substantially greater than the first mass portion dimension, and a total mass of the second mass portion may be greater than or equal to three times a total mass of the first mass portion. Other examples and embodiments may be described and claimed.

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.

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.

A golf club head includes a club body and a resting face angle adjuster. The club body includes a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel. The sole includes a sole surface. The resting face angle adjuster includes an adjustment member having a keel surface, and a recess formed in the sole such that a portion of the sole surface at least partially bounds the recess. The adjustment member is disposed in the recess and positionable between a first adjustment position and a second adjustment position. In the first adjustment position, the keel surface is at a first distance relative to the portion of the sole surface. In the second adjustment position, the keel surface is at a second distance relative to the portion of the sole surface not equal to the first distance in the direction.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a body portion with an interior cavity, a face portion, a first port, and a second port connected to the interior cavity. The second port includes first and second openings, a second-port first portion, and a second-port second portion. The second-port first portion extends from the first opening to the second opening, and the second-port second portion extends from the second opening to the interior cavity. A portion of the interior cavity below a horizontal midplane of the body portion and between the second port and a heel portion edge of the body portion is closer to an outer surface of the back wall portion than the second opening of the second port. Other examples and embodiments may be described and claimed.

Putter type club head with vertical groove patterns are described herein. A putter type club head comprises a putter face having a plurality of first curved grooves and a plurality of second curved grooves. The first curved grooves and the second curved grooves intersect each other at a plurality of points across the putter face. The width and depth of the first curved grooves and the second curved grooves can vary across the putter face in a direction extending from a heel end to a toe end, and/or in a direction extending from a top rail to a sole. The curved groove pattern provides consistent ball speed performance for any impact location on the putter face.

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head may include a cavity having an opening and an interior structure defined by a wall portion and a base portion. A hosel portion may include an insert portion and a neck portion extending therefrom. The hosel portion may be attached to the body portion by an interference fit between the neck portion and the opening of the cavity. The insert portion may be received inside the cavity and may be spaced apart from the interior structure of the cavity. A space between the insert portion and the interior structure of the cavity may be partially or entirely filled with an adhesive to hold the hosel portion in place. Other examples may be described and claimed.

A forged golf club head is disclosed. More specifically, the present invention discloses a forged golf club head with an improved scoreline profile that not only has improved precision, but also has an improved geometry to help enhance the performance of the golf club head.

Some embodiments include a golf club head. The golf club head includes a front body having a front body front portion with a front body front surface and having a front body rear portion, and includes a rear body having a rear body front portion, a rear body rear portion, and multiple protrusions. The golf club head is configured such that (i) when the front body front surface strikes a golf ball with a first amount of force, the front body deflects toward the rear body with a first amount of deflection, and (ii) when the front body front surface strikes the golf ball with a second amount of force less than the first amount of force, the front body deflects toward the rear body with a second amount of deflection greater than the first amount of deflection. Other embodiments of related club heads and methods are also disclosed.
