Our Roll Control Face™ is engineered with a distinct groove profile to propel the ball into a true roll faster while giving golfers the softest feeling milled putter in golf. By removing 55% of the material from the putter’s face, we’ve created a face milling that results in less mass hitting the golf ball, which equates to a softer feel. This is exclusive to our INOVAI and Studio Stock lines. It’s an asymmetrical groove design that is made for golfers with an aggressive putting style.
