Abstract: An improved striking face of a golf club head is disclosed. More specifically, the present invention relates to a striking face having one or more thickened central region located near a “region of excessive performance” on the striking face, a thinned perimeter portion located around a perimeter of the striking face, and a transition region that transitions from each of the one or more thickened central region towards the thinned perimeter portion. The improved striking face could be made out of a material having a high strength and low hardness such as ATI-425®.

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 first material and at least one weight adjustment portion monolithically encased within the body portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations. The present invention also includes a combination of lightweight and heavy density weight adjustment portions that could be introduced towards the final forging step of the co-forging process, allowing for more flexibility in the selection of materials.

Abstract: A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity, a riser extending into the cavity, and a ledge extending from the edge of the riser. The ledge may define a first channel and a second channel that extend around the ledge. The first channel is filled with adhesive to secure the inner portion of the crown to the ledge. The inner portion of the crown is attached to the ledge such that the opening is covered by the inner portion of the crown. The golf club head may also have a sole comprising an inner sole portion and an outer sole portion.

Abstract: A forged golf club face has a continuous outer layer of a first material encasing at least one inner layer made of second material. The materials may have differing properties, such as Young's Modulus, density, and strength properties, among others. By incorporating the different materials into the outer layer and the inner layer, the coefficient of restitution (COR) of the golf club face is improved without sacrificing durability. The club face is forged from a pre-formed billet having at least one monolithically encased inner layer.

Abstract: A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity, a riser extending into the cavity, and a ledge extending from the edge of the riser. The ledge may define a first channel and a second channel that extend around the ledge. The first channel is filled with adhesive to secure the inner portion of the crown to the ledge. The inner portion of the crown is attached to the ledge such that the opening is covered by the inner portion of the crown. The golf club head may also have a sole comprising an inner sole portion and an outer sole portion.
