Abstract
A golf club head includes a body member having a ball striking face, a crown, a toe, a heel, a sole, a back and a hosel region, located at the intersection of the ball striking face, the heel, the crown and the sole. The body member may have a first cross-section having a first airfoil-shaped surface in the heel. The first cross-section may be oriented at approximately 90° from the centerline of the club head. The body member may have a second cross-section having a second airfoil-shaped surface. The second cross-section may be oriented at approximately 45° or at approximately 70°. The airfoil-shaped surfaces may be defined by spline points or by equations. A golf club including the golf club head is also provided.
