Abstract
The present invention is directed to a golf club head with an improved striking surface. The grooves are machined into the strike surface with tight tolerances and angled relative to a leading edge of the golf club head. The sole of the golf club head is contoured so that the effective bounce and leading edge height are controlled when the golf club head is rotated to an opened orientation.
