subject: the Groove Rule [print this page] To golfers?everything they used has its standard rule . Lets see the groove rule. According to the USGA, there are two key components to the groove rule: The volume of grooves is reduced. Groove edge sharpness is reduced for clubs with lofts greater than or equal to 25 degrees (about a 5-iron or above).(there are golf clubs for sale) Writing at golfdigest.com, Jaime Diaz had an excellent description of how grooves on a club face can affect the ball. Grooves on irons exist to create backspin that assists in control, he wrote. Until 1984 uniform tooling and rules that regulated spacing produced a relatively narrow groove that was cut in a V shape from top to bottom. That year, Ping founder Karsten Solheim, under what he contended were the same parameters, created grooves that were more U-shaped and wider. It was soon found that Pings grooves which came to be known as square grooves imparted more spin than conventional irons, particularly from the rough. The reason is the same one that applies to rain tires. The bigger grooves in the tire displace more water, allowing the rubber to make more contact with the asphalt and thus have better traction. In the same way, grooves with more volume and less space between them take in more grass and moisture, leaving less debris between the steel surface and the cover of the ball, allowing more backspin and control. a joke:I Imagine Things The drunk was floundering down the alley carrying a box with holes on the side. He bumped into a friend who asked, "What do you have in there, pal?" "A mongoose." "What for?" "Well, you know how drunk I can get. When I get drunk I see snakes, and I'm scared to death of snakes. That's why I got this mongoose, for protection." "But," the friend said, "you idiot! Those are imaginary snakes." "That's okay," saidthe drunk, showing his friend the interior of the box, "So is the mongoose."
