Abstract: 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 having a toe portion, a heel portion, a front portion, a rear portion, a top portion, and a sole portion. A retention cavity is located at the sole portion and includes an opening and a plurality of interior side walls connected to the opening. The plurality of interior side walls define two or more ball retention areas configured to frictionally engage at least a portion of a golf ball within the retention cavity. The two or more ball retention areas are located at or proximate the opening and frictionally engage the golf ball along a ball circumference located above an equator of the golf ball. Other examples and embodiments may be described and claimed.

Abstract: Embodiments of a blade style putter type club head comprising enlarged physical features such as an enlarged length, height, and depth. The enlarged physical features, specifically the enlarged length allows mass to be positioned further from the center of gravity. The positioning of the mass away from the center of gravity allows the blade style club head to achieve an increased MOIyy creating a more forgiving blade style putter type club head.

Abstract: A shim or badge is affixed to a golf cub body to produce a cap-back iron, giving the appearance of a hollow-body iron. In this way, the golf club can be manufactured with the performance benefits of a game improvement iron, while providing the appearance of a blade, player's iron, and/or a hollow-body iron. For example, by using a lightweight and rigid shim or badge to close a cavity opening and extend into the toe portion of the golf club body, the golf club head can provide increased stiffness in the topline, while lowering CG. Various shim or badge arrangements and materials can be used, and a filler material and/or damper can be included within the cavity to improve sound and feel, while minimizing loss in COR.
