Abstract
Abstract A metal golf club head comprising a face portion, a wing extending from the upper end of said face portion rearwardly thereof. The upper surface of said wing is contoured for coincidence with the radial trajectory of the golf club head during down swinging thereof. A toe portion extends rearwardly from the outer end of the face portion, a sole portion extends rearwardly from the lower end of said head with there being a rearwardly opening recess in said club head defined by the wing, sole portion, toe portion, rearward surface of said face portion and a heel portion at the inner end of said face portion. Said wing and said toe portion may be constructed independently of said head and secured to the face portion thereof as by suitable fasteners.
