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 8):
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; a rear surface opposite the ball striking surface, the rear surface having a muscle portion extending from the heel to the toe; an interface surface adjacent an upper edge of the muscle portion, wherein the interface surface includes a convergence point located closer to the toe than the heel, and further includes a first interface surface extending from the heel to the convergence point and a second interface surface extending from the convergence point to the toe, wherein the first interface surface and the second interface surface form an interface angle at the convergence point, wherein the interface angle is an obtuse angle, wherein the interface angle is between approximately 115 degrees and 155 degrees; and 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 interface; and the muscle portion height increases at a greater rate from the ball striking centerline to the toe compared to the heel to the centerline.
