NOTICE OF COPYRIGHTS AND TRADE DRESS [0003] A portion of the disclosure of this patent document contains material which is subject to copyright protection. This patent document may show and/or describe matter which is or may become trade dress of the owner. The copyright and trade dress owner has no objection to the facsimile reproduction by anyone of the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright and trade dress rights whatsoever. BACKGROUND [0004] 1. Field [0005] This disclosure generally relates to golf clubs, and, more particularly, to clubs having a metal head, commonly called "irons". [0006] 2. Description of the Related Art [0007] Current regulations call for a maximum of 14 golf clubs to be used by a golfer during a round of golf. Typically, a set of golf clubs ranges from a putter through so-called "iron" clubs designed for various distances and degrees of loft to so called "wood" clubs, which are used for the longest distance shots. The putter, of course, is used for the final shots taken on or around a putting green. [0008] A significant fraction of golf shots are made from the region surrounding the putting green. In the area around the putting green, the desired shot distance may not allow the use of a full swing with any of the 14 traditional clubs. Hitting shots with a variety of partial-strength swings is difficult for both novice and expert golfers. DESCRIPTION OF THE DRAWINGS [0009] FIG. 1 is a side view of the head and lower portion of the shaft of a golf club. [0010] FIG. 2 is a front view of the head and lower portion of the shaft of a golf club. [0011] FIG. 3 is a back view of the head and lower portion of the shaft of a golf club. [0012] FIG. 4 is a side view of the head and shaft of a golf club. [0013] Throughout this description, elements appearing in figures are assigned three-digit reference designators, where the most significant digit is the figure number and the two least significant digits are specific to the element. An element that is not described in conjunction with a figure may be presumed to have the same characteristics and function as a previously-described element having a reference designator with the same least significant digits. DETAILED DESCRIPTION Description of Apparatus [0014] Referring now to FIG. 1, a golf club may include a golf club head 110 and a shaft 180 which is only partially shown in FIG. 1. The golf club head 110 may include a relatively thick body 120 and a generally planar face 160. The body 120 may have an undersurface, commonly called the "sole", including a generally flat ground contact area 122, a forward portion 124, and a trailing portion 126. The forward portion 124 may be slightly curved, rising at an approximately 8.degree. angle from the ground contact area 122 to a leading edge 128 where the forward portion 124 meets the face 160. The trailing portion 126 may rise at a slight angle, approximately 2.degree. or 3.degree. between the ground contact area 122 and the back of the body 120. [0015] The club head 110 may be provided with a hosel 140 having an opening for receiving the lower end of the club shaft 180. The hosel 140 may be located on the body 120 such that the hosel opening is located behind the plane of the face 160. The hosel 140 may be located on the body 120 substantially and directly behind the face 160. As shown in FIGS. 1, 2 and 3, for example, the hosel 140 is on the right-hand side of the head 110 (when viewed from the front) which means this would be made for a right-handed golfer. For a left-handed golfer, the hosel 140 would be on the opposite side from the showing in these figures. [0016] As shown in FIG. 1, the face 160 has a loft angle of 48 degrees. Within this description, the loft angle is defined to be the angle of the face with respect to a line normal to the ground contact area 122 of the sole, measured in degrees. The ground contact area 122 may be approximately horizontal when the club is held in a resting position. Thus the loft angle may be approximately the angle between the face and vertical when the club is held in a resting position. A 48-degree loft angle may be useful for shots taken in the immediate vicinity of a putting green. The loft angle between the face 160 and a line normal to the ground contact area 122 may be between 10 degrees and approximately 70 degrees. Club heads having different loft angles will impart different loft to the ball when driving it from the fringe or the rough area surrounding the green. [0017] FIG. 2 shows a front view of a golf club 200, which may be the golf club 100, having a club head 210 and a shaft 280 which is only partially visible. Except for a hosel (not visible) to which the shaft 280 is attached, the club head 210 may be symmetrical about a vertical mid-plane. The club head 210 may have a face 260, which may be provided with a plurality of transverse grooves 265. The transverse grooves may be cut into the face 260 with selected depths and widths to help impart spin to a golf ball struck with the face 260. [0018] FIG. 3 shows a back view of an exemplary golf club 300, which may be the golf club 100 or 200, having a club head 310 and a shaft 380 which is only partially visible. The club head 310 may include a body 320. The shaft 380 may be joined to the club head 310 at a hosel 340 which may include an opening in the body 320 to receive the end of the shaft 380.
