发明名称 Golf club having angular grooves
摘要 A method of imparting a directional corrective horizontal spin component to a golf ball includes providing a plurality of golf clubs each having a golf club head with a ball striking face having grooves angled relative to a sole of the club. Each club has a select loft angle and a groove angle which varies as a function of the select loft angle. The method further includes selecting a club having a desired loft angle for striking a golf ball, aligning the club head with the sole perpendicular to a desired line between the ball and the target and striking the golf ball with the sole perpendicular to the desired line between the ball and the target.
