Putters are a special class of clubs with a loft not exceeding ten degrees, designed primary to roll the ball along the grass, generally from a point on the putting green toward the hole. Contrary to popular belief, putters do have a loft (often 5 ° from truly perpendicular at impact) that helps to lift the ball from any indentation it has made. Newer putters also includes grooves on the face to promote roll rather than a skid off the impact.
This increases rolling distance and reduces bouncing over the turf. Putters are the only class of club allowed to have certain features, such as two striking faces, non-circular grip cross-sections, bent shafts or hosels, and appendages designed to aid players’ aim.
