Abstract: In general, aspects of this invention relate to blade-type iron golf clubs or golf club heads. The blade-type golf club head may comprise a body forged of a metal material. The body may include a hosel, a top surface, a sole, a heel, a toe, a ball striking surface, and a rear surface opposite the ball striking surface. The rear surface may have an upper blade portion and a lower muscle portion with the upper blade portion separated from the lower muscle portion by a blade interface. The lower muscle portion may have a muscle portion surface are that includes a heel muscle surface area measured from the ball striking centerline to the heel and a toe muscle surface area measured from the ball striking centerline to the toe. The toe muscle surface area may make up at least 60% of the muscle portion surface area. The mass distribution of the lower muscle portion moves the center of gravity of the club head closer to the face center location.

Abstract: A golf club head with a sole having a low stiffness compliance zone, which allows the face to deflect downward upon impact with a golf ball, is disclosed herein. The compliance zone comprises a plurality of through openings that are filled with one or more filler pieces comprising a low modulus material, all of which are located within three inches of a face section measured along a front-to-back axis of the golf club head.

Abstract: A putter-type golf club comprising an electrical component is disclosed herein. The electrical component comprises an integrated circuit having a gyroscope, a magnetometer, and a BLUETOOTH low energy (BTLE) radio, and at least one battery. A body is composed of an epoxy material, and the body encompasses the electrical component.

Abstract: Described are embodiments of golf club heads having an internal cavity and features that cause the golf club head to have an improved acoustic performance when striking a golf ball. Some embodiments include one or more weight tracks and/or weight ports formed in the sole for receiving adjustable weights. The golf club heads can include one or more internal ribs, thickened wall regions, and/or posts positioned within the cavity that increase the rigidity of the club head and improve the acoustic performance of the club head when striking a ball.

Abstract: A golf club head with a central body component is disclosed herein. The central body component includes a crown portion and a sole portion. The crown portion is composed of a continuous carbon fiber reinforced epoxy material. The sole portion is composed of a chopped carbon fiber reinforced vinyl ester sheet molding compound material. The central body component has a front opening and a rear opening with a hollow interior.

Abstract: In a golf ball having a core, an envelope layer, an intermediate layer and a cover, the core is formed of a rubber composition and the envelope layer, the intermediate layer and the cover are each formed of a resin composition. The core, the envelope layer-encased sphere, the intermediate layer-encased sphere and the ball have respective initial velocities which together satisfy the following three conditions: (initial velocity of ball)<(initial velocity of intermediate layer-encased sphere), (initial velocity of intermediate layer-encased sphere)?(initial velocity of envelope layer-encased sphere)?0.60 m/s, and 0.50?(initial velocity of envelope layer-encased sphere)?(initial velocity of core)?1.08 m/s. This golf ball can achieve a superior distance on shots with a utility club and with irons, and exhibits a good durability to repeated impact, a good controllability in the short game and a good feel at impact.
