First Claim
1. An iron type golf club head comprising a club face, said club face defining a plane and having grooves, a back surface on the opposite side of said club head from the club face, a toe portion, a heel portion, a top edge, and a sole portion extending generally between the heel portion and the toe portion, wherein said club head comprises:
- (a) a main body having an exterior periphery comprising an end surface along said toe portion, said end surface along said toe portion being oriented generally perpendicular to the plane defined by said club face and an end surface along said heel portion opposite the end surface along said toe portion, said main body at least partially comprised of a material having a first specific gravity; and
(b) a weighting system joined to a portion of the exterior periphery of the main body of said club head, said weighting system comprising at least one higher specific gravity weighting portion having a specific gravity greater than said first specific gravity, wherein said at least one higher specific gravity weighting portion is joined to the end surface along said heel portion, wherein at least a portion of said higher specific gravity weighting portion is at least partially located in a recess formed in the outer surface of said heel portion of said main body, wherein said higher specific gravity weighting portion being located at least partially laterally outward, in a direction generally parallel to the grooves in the club face, of said portion of the exterior periphery of said main body to which it is joined, and said higher specific gravity weighting portion is free of lead tape.

Abstract
Golf clubs having improved features and a golf swing training device are disclosed. In one embodiment, the golf club has a club head made of at least one material having a first specific gravity, and at least one weighting portion that has a higher specific gravity than the first specific gravity of the material forming the main body of the club head. In another embodiment, the golf club has a club head of the “iron” type, and the club head has a sole that is provided with “bounce” thereon. In another embodiment, the golf club has a club head of the “iron” type that has a configuration that provides it with improved ability to cut through the “rough” on the golf course. In another embodiment, the golf club has a club head having a club face with at least one portion thereof that has a thickness that is modified to account for a groove in the striking surface of the club face. In another embodiment, correlated golf clubs are provided in which the club face is opened or closed relative to at least one other club within a set of golf clubs. The golf swing training device has a structure that is attached to the golf club and extends outward from the front of the golf club that makes the rotation of the golf club shaft and/or club face more visible to the golfer.

13. An iron type golf club head comprising a club face, said club face defining a plane and having grooves, a back surface on the opposite side of said club head from the club face, a toe portion, a heel portion, a hosel extending upward from said heel portion for receiving a golf club shaft, a top edge, and a sale portion extending generally between the heel portion and the toe portion, wherein said club head comprises:
-
(a) a perimeter weighted main body wherein the back surface of said club head comprises a central region which has a cavity therein, wherein the cavity is at least partially surrounded by thicker portions on the back surface of said club head, said main body having perimeter weighted portions along one or more of the heel portion, the toe portion, the top edge, and the sole of the club head, wherein each of said perimeter weighted portions has an outer surface, said main body being at least partially comprised of a material having a first specific gravity, said main body having an outer surface, wherein a recess is formed in at least one of the outer surfaces of said perimeter weighted portions at said toe portion or said heel portion, wherein said outer surface along said toe portion is oriented generally perpendicular to the plane defined by said club face, and the outer surface at said heel portion is opposite the outer surface along said toe portion, and said recess forms an opening in the outer surface of said main body; and (b) a weighting system joined to the outer surface of the main body of said club head, said weighting system comprising at least one higher specific gravity weighting portion having a specific gravity greater than the first specific gravity of said material comprising said main body, wherein at least a portion of said higher specific gravity weighting portion is at least partially located in the recess formed in the outer surface of at least one of the perimeter weighted portions along said toe portion or said heel portion of said main body, and at least a portion of said higher specific gravity weighting portion protrudes laterally outward, in a direction generally parallel to the grooves in the club face, beyond the portion of said main body defining said recess. - View Dependent Claims (14, 15)
