Abstract

A golf club head is described having a club head portion, a shaft portion connected to the club head portion, and a grip portion connected to the shaft portion. The club head portion has a heel portion, a sole portion, a toe portion, a crown portion, a hosel portion, and a striking face. The striking face has a center face roll contour, a toe side roll contour, a heel side roll contour, a center face bulge contour, a crown side bulge contour, and a sole side bulge contour. The toe side roll contour is more lofted than the center face roll contour. The heel side roll contour is less lofted than the center face roll contour. The crown side bulge contour is more open than the center face bulge contour, and the sole side bulge contour is more closed than the center face bulge contour.
