Abstract: An iron-type golf club head is provided with a body having a volume less than 120 cc. The body can include a sole portion with two or more slots extending upwardly into the body through the sole portion into a cavity behind a face portion. A damper can be included in the cavity and in contact with a rear surface of the face portion. The club head can have a maximum CT proximate to the ideal striking location and a CT dropoff of no more than 110 ?s at a point located between a first and second scoreline proximate to the sole portion. The club head can also have a CG along the y-axis (CG-y) between 0.25 mm and 20 mm and a CG along a positive z-up axis (CG-z) between 12 mm and 25 mm.

Abstract: Disclosed herein are embodiments of iron-type golf club heads that include weight reducing features in the topline region of the club head that facilitate changing the Z-up location of the club head. In some embodiments the body includes a weight reducing feature in a topline weight reduction zone of the club head that extends over the entire face length from the par line to the toe portion ending at approximately the Z-up location of the iron type golf club head. The weight reducing feature results in a mass savings of about 2 g to about 20 g, and a Zup shift of about 0.5 mm to about 2.0 mm.

Abstract: Iron-type golf club heads are disclosed having a heel portion, a sole portion, a toe portion, a top-line portion, a front portion, a rear portion, and a striking face. The iron-type golf club heads include a localized stiffened region that is located on the striking face of the club head such that the localized stiffened region alters the launch conditions of golf balls struck by the club head in a way that wholly or partially compensates for, overcomes, or prevents the occurrence of a rightward deviation. In particular, the localized stiffened region is located on the striking face such that a golf ball struck under typical conditions will not impart a right-tending sidespin to the golf ball.

Abstract: An iron-type golf club has a body that defines a rear void. The face portion includes an ideal striking location that defines the origin of a coordinate system. The body includes a central region in which ?25 mm<x<25 mm. The sole portion that is contained within the central region includes a forward sole region located adjacent to the face portion and a sole bar located rearward of the forward sole region, with the forward sole region defining a wall having a minimum forward sole thickness TFS and the sole bar defining a body having a maximum sole bar thickness TSB, such that 0.05<TFS/TSB<0.4. The sole portion includes a slot extending in a substantially heel-to-toe direction of the sole portion, the slot defining a portion of a path that extends through the sole portion and into the rear void. The slot is at least partially filled with a filler material.

Abstract: An iron-type golf club head is provided with a body having a volume less than 120 cc. The body can include a sole portion with two or more slots extending upwardly into the body through the sole portion into a cavity behind a face portion. A damper can be included in the cavity and in contact with a rear surface of the face portion. The club head can have a maximum CT proximate to the ideal striking location and a CT dropoff of no more than 110 ?s at a point located between a first and second scoreline proximate to the sole portion. The club head can also have a CG along the y-axis (CG-y) between 0.25 mm and 20 mm and a CG along a positive z-up axis (CG-z) between 12 mm and 25 mm.

Abstract: A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. In some embodiments, the crown includes a lattice-like structure having thin regions surrounded by a web of relatively thicker regions. In some embodiments, the club head includes one or more stiffening tubes attached between the sole and the crown to improve the acoustic performance of the golf club head.
