Abstract
The putter face insert of the present invention reduces or eliminates backspin, and in some circumstances even imparts topspin, of a golf ball after impact with the putter face by including a contact surface with uniform thickness and at least one backing having non-uniform thickness. Generally, reducing initial backspin improves distance control and directional consistency of a golf ball when putting.
