Abstract

A golf club iron having a head center of gravity that is low and forward enough to provide a better swing, good striking and swinging feel, and improved ball flight is disclosed. The iron has a recess in a leading edge region and a high density insert disposed within the recess to achieve the desired center of gravity location.

Claims (28)

1. A golf club comprising:

wherein the face has a lower portion adjacent the sole,

wherein the recess is located in at least part of the lower portion of the face and extends into at least part of the sole, and
