  • Publication number: 20020049096
    Abstract: 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.

  • Patent number: 6348010
    Abstract: A golf club has grooves across its face that are angled from an upper face section positioned relatively toward a toe of the club to a lower face section positioned relatively toward the heel with respect to the sole of the golf club instead of being parallel with a sole of the club. The angled grooves cause a sideways spin to be imparted to a struck golf ball. In one application, the angled grooves impart a spin that corrects for what would otherwise be a slice. The grooves can be at different angles, depending upon the golf club and the application. In an embodiment, the low irons and woods will have the grooves at a relatively higher angle than the mid irons, which will have the grooves at a higher angle than the approach irons and wedges. Clubs having such angled grooves can be structured according to USGA or other rules, but need not be.
