O Works has the Microhinge insert which generates more topspin and roll at impact regardless of your stroke. The Microhinge insert is moulded into our Thermoplastic Elastomer Feel layer which generates great feel and allows the ball to start rolling better from the moment of contact. The putter is face balanced which suits players who do not rotate the face too much but rather have a straight putting stroke, or those who want to reduce head rotation in their putting stroke.
