Abstract: The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and significant tungsten weight members coupled to at least the toe and a heel weight member coupled in a hosel cavity.

Abstract: A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discrete orientations between the shaft and club head.

Abstract: The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and significant tungsten weight members coupled to at least the toe via a mechanical fastener inserted through the face.

Abstract: A golf club head including a plurality of face support tabs that are attached to an interior surface of the perimeter of a golf club head. The face support tabs are in contact with a rear surface of a striking face and, in some examples, are fastened to the rear surface of the striking face. Where the face support tabs are fastened to the rear surface of the striking face, the edges of the striking face are not directly fastened to the perimeter of the golf club head. Where the face support tabs are not secured to the rear surface of the striking face, the striking face is fastened to the perimeter of the club head body and the face support tabs are preloaded so as to exert a force against the rear surface of the striking face even when the striking face is in a neutral position.

Abstract: A golf club head having a golf club head body and an inner wall structure. The club head body includes a back portion, a striking face, a sole, and a topline. The inner wall structure is at least partially in contact with a rear surface of the striking face. The inner wall structure also has a fixed end and an unfixed end. The golf club head is also configured such that the portion of the inner wall structure in contact with the rear surface of the striking face may slide against one another. The golf club head may also include a sole channel, and the fixed end of the inner wall structure may be attached to either a front edge or back edge of the sole channel.

Abstract: A co-forged iron type golf club is disclosed. More specifically, the present invention discloses a co-forged iron type golf club with the body portion made out of a face portion and a back portion and at least one weight adjustment portion monolithically encased within the back portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations.

Abstract: An iron-type golf club head has a club head body that includes a back portion, a topline, a sole portion, and a striking face. The golf club head also may include a rib that extends from the back portion of the club head body to a rear surface of the striking face. A symmetric portion of the striking face is defined by contact with the topline, the sole portion, and the rib. A second rib may also be included in the golf club head and the symmetric portion of the striking face is defined by contact with the topline, the sole portion, the first rib, and the second rib. A flex support structure may also be incorporated into the golf club head. The flex support structures may have multiple profiles that contact the rear surface of the striking face at differing deflection depths.

Abstract: A golf club head has a striking face. A ledge extends from the perimeter contact rim of the golf club head. The striking face is secured to the club head body proximate the rim. There is a gap between the striking face and the ledge. The inner wall's perimeter edge is disposed in the gap and is in contact with the ledge. The rear surface of the striking face is in contact with a portion of the inner wall.

Abstract: A golf club head with a multi-level badge is disclosed herein. More specifically, the golf club head in accordance with the present invention is an iron type golf club head with a multi-level badge that on one level contacts a rear surface of the striking face of the golf club head, and a second level of the multi-level badge contacts a rear surface of a cavity created by the chassis of the golf club head.

Abstract: The present invention is directed to a set of golf clubs comprising long irons, mid-irons and short irons. The irons have a progressive horizontal CG location. Preferably, the long and MID irons have a CG located between about 1 mm and 3 mm towards the hosel and the short iron CG is located between about 3 mm and 4 mm toward the hosel. Further the irons have a substantially constant blade width with progressively decreasing scoreline width.

Abstract: An iron type golf club head comprising a blade portion located near a terminal end of said iron type golf club head forming a cavity near a bottom sole portion of said blade portion; a hosel portion located near a proximal end of said iron type golf club head; wherein said first material has a yield strength greater than about 570 MPa; wherein said second material has a yield strength less than about 570 MPa.
