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 1):
An iron-type golf club head comprising:\n a top surface, a sole, a heel, and a toe; a ball striking surface having a ball striking area, wherein the ball striking surface area defines a heel-side boundary line, a toe-side boundary line, and a ball striking centerline located equidistant between the heel-side boundary line and the toe-side boundary line; and a rear surface opposite the ball striking surface, the rear surface having a blade portion and a muscle portion with the blade portion separated from the muscle portion by a blade interface, wherein the blade portion and muscle portion laterally extend across the rear surface and further with the blade portion extending from the top surface to the blade interface and with the muscle portion extending from the blade interface to the sole; 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 first blade interface extends from the heel to the convergence point and the second blade interface extends from the convergence point to the toe, wherein the first blade interface and the second blade interface form an interface angle at the convergence point, wherein the interface angle is an obtuse angle; the muscle portion comprises a vertical muscle portion height measured parallel to the striking surface from a leading edge of the sole to an intersection of the muscle portion and the blade interface; and the muscle portion height increases at a greater rate from the ball striking centerline to the toe than from the heel to the ball striking centerline.
