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. An average height of the lower muscle portion from the ball striking centerline to the toe-side boundary line may be approximately twice an average height of the lower muscle portion from the heel-side boundary line to the ball striking centerline. The mass distribution of the lower muscle portion moves the center of gravity of the club head closer to the face center location.

Claim (Index 14):
An iron golf club comprising:\n a blade-type golf club head comprising a body forged of a metal material, the body having a hosel, a top surface, a sole, a heel, and a toe, the blade-type golf club head further comprising a ball striking surface; a rear surface opposite the ball striking surface, the rear surface having an upper blade portion and a lower muscle portion with the upper blade portion separated from the lower muscle portion by a blade interface; wherein the blade interface includes a first blade interface and a second blade interface intersecting the first blade interface at a convergence point located closer to the toe than the heel, wherein the second blade interface extends upward at an interface angle from the convergence point and between the first blade interface and the second blade interface, wherein the first blade interface extends parallel to the sole, and wherein the upper blade portion and lower muscle portion extend across the rear surface from the heel to the toe and further with the upper blade portion extending from the top surface to the blade interface and with the lower muscle portion extending from the blade interface to the sole; wherein the upper blade portion has a generally uniform thickness from the heel to the toe, and the lower muscle portion has a thickness greater than an upper blade portion thickness; wherein the rear surface comprises an indentation positioned within the upper blade portion; and a shaft that attaches to the club head at the hosel.
