Embodiment Construction

[0019]As shown in FIGS. 1-10, an iron-type golf club head in accordance with the present invention is generally designated 20. The club head 20 is a cavity-back iron and includes a body 22 having a heel end 24 and a toe end 26. The body 22 has a front wall 28 for contacting a golf ball and a hosel 30 for receiving a shaft, not shown. In a preferred embodiment the golf club head 20 is composed of a stainless steel, however, those of ordinary skill in the art will appreciate that the golf club head 20 may also be composed of other materials, such as carbon steel, titanium, titanium alloy, zirconium or zirconium alloy.

[0020]The front wall 28 of golf club head 20 has a ball-striking surface 40 and a back surface 42. The ball-striking surface 40 has a plurality of scorelines 44 formed therein. In a preferred embodiment the top of the hosel 30 is lower than the toe end of the front wall 28, thereby lowering the center of gravity of the club head 20.

[0021]The golf club head 20 also has a t...

Abstract

The invention creates a unique combination of head shape and surface friction coefficients that minimize the bad effects of turf impact. The invention is an iron-type golf club head having a body composed of a stainless steel material and having a front wall, a sole portion and an undercut recess. The sole portion extends rearward from the front wall and has a main surface, a stepped surface and an edge between the main surface and the stepped surface.
