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 extend in a general vertical direction, and 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 vertical 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 top portion of a golf club head includes an alignment aid having a first plurality of strip portions and a second plurality of strip portions bounded by a virtual outline. The first plurality of strip portions have different surface areas. The second plurality of strip portions have different surface areas. The first plurality of strip portions and the second plurality of strip portions touch or border upon the virtual outline. The first plurality of strip portions are spaced apart in a rear-to-front direction of the golf club head and are ordered by decreasing surface area. The second plurality of strip portions are spaced apart in the rear-to-front direction and are ordered by decreasing surface area. Other examples and examples may be described and claimed.

A putter-chipper golf club may include: a body 110 including a coupling groove portion 110a having a through-hole formed therein; a variable face 120 disposed on one side of the body 110 and configured to function as a putter face or a chipper face; a spring 130 disposed on the circumference of a part of the coupling protrusion portion 120a; and a face cap 150 disposed adjacent to the spring 130. When the coupling groove portion 110a of the body 110 and the coupling protrusion portion 120a of the variable face 120 are disengaged from each other by pulling the variable face 120 from the body 110 toward one side, the golf club may be switched to a putter or a chipper through rotation of the variable face 120.

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a top portion of a golf club head may include an alignment aid having a first plurality of strip portions and a second plurality of strip portions. Each strip portion of the first plurality of strip portions and each strip portion of the second plurality of strip portions have a quadrilateral shape with a diagonal side. The diagonal sides of the first plurality of strip portions are aligned with one another to generate a first focal axis and the diagonal sides of the second plurality of strip portions are aligned with one another to generate a second focal axis that meets with the first focal axis at a focal point. Other examples and examples may be described and claimed.

Golf clubs having weighting systems with movable weights are disclosed. In one embodiment, the golf club head includes: a main body having a periphery; and a weighting system including a movable weight, wherein the weighting system is configured to allow the weight to move between: a first position inward of the periphery of the main body; and a second position wherein at least a portion of the weight is located outward of the periphery of the main body. In other cases, the movable weight need not be movable to a position that is outward of the periphery of the main body.

Embodiments of grooves and face inserts of golf club heads and methods to manufacture grooves and face inserts of golf club heads are generally described herein. Other embodiments may be described and claimed.

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 front portion. A face portion may be coupled to the front portion. The face portion may include a central strike portion and a perimeter. A plurality of projections may extend from the face portion to provide a ball striking surface for impacting a golf ball. The plurality of projections may be aligned in one or more directions across the face portion and may progressively increase in size in any direction from the central strike portion to the perimeter of the face portion. Other examples and examples may be described and claimed.

Customizable golf putters are disclosed. The putters include a putter face; a putter head that is configured to be reversibly connected to the putter face (with the putter head being selected from a plurality of different putter head styles); and a hosel that is configured to be reversibly connected to any of a plurality of hosel receiving channels that are accessible on a top surface of the putter head (the hosel is also selected from a plurality of different hosel styles). The golf putters further include a threaded shaft connector that is configured to reversibly connect the hosel to a putter shaft. In addition, the golf putters include one or more peg fillers, which are configured to be inserted into empty hosel receiving channels.

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

Embodiments of putter golf club heads with an elastomer is enclosed herein. Other embodiments and methods may be described and claimed.
