Abstract
Golf club heads are disclosed which have face surface shapes which are designed so as to reduce the scatter of the points where the ball stops after a hit, as compared to face surface shapes of prior art. This is accomplished by use of optimum face surface shapes which respect the USGA requirement for no degree of concavity. The face surface shapes disclosed are different in upward directions from the hit center to the face surface shapes in downward directions.
