Rolling a ball with your hand is generally more accurate than hitting it with a board. It's a simple observation, but one that the Odyssey O-Works Microhinge Putter applies to golf for the first time. Its special insert is covered with tiny hinges that flex and rebound independently, sending the ball on a smooth roll just like an army of tiny hands. Behind it sits a layer of soft thermoplastic elastomer for outstanding feel, and the bottom is home to two weights that help keep your stroke on line. Available in four blade models, as well as four mallets.
