Abstract
The present invention is a unique advanced hybrid iron type golf club. The club is characterized by a long blade length with a long heel blade length section, while having a small club moment arm, Zcg, and volume, and producing a high moment of inertia. The golf club incorporates the discovery of unique relationships among key club head engineering variables that are inconsistent with merely striving to obtain a high moment of inertia using conventional golf club head design wisdom.
