The Odyssey Metal-X Arm Lock putter is designed with a forward lean of 4° to ensure that it can be used as an extension of your lead arm. This promotes incredible stability and consistency through the stroke. The Metal-X insert provides the crisp feedback of a metal striking surface, coupled with the benefits of a softer urethane inner layer for amazing feel. The face pattern is unlike any other in golf and generates the truest roll in the game. The ovals on the face will actually create a mechanical lock with the golf ball's dimples at impact, creating friction and imparting an incredibly consistent roll on the ball allowing for high precision distance control. It features a Midnight Black Finish inspired by the feedback from Tour players and Tour-tuned weight ports in the sole to optimize the putterhead with the shaft length. The headweight optimization helps to create the ideal balance to maximize feel, control and accuracy.
