Abstract
A golf club head is characterized by stepped grooves in the striking face thereof. The grooves may have a V-shape or a U-shape. The V-shaped grooves have side walls that intersect at the bottom of the grooves, while the U-shaped grooves have side walls that terminate at opposite ends of a bottom wall, which preferably is parallel to the striking face. At least one side wall of the grooves contains at least one step portion, so that the grooves have a stepped configuration. The stepped grooves impart more consistent spin to a golf ball when struck by the club head.
