The Dual Durometer Putter Face Insert Patent
Everyone has heard the marketing hype regarding dual durometer golf grips, but what about putter face inserts? This week PING (actually Karsten) was granted a patent for just that. The patent is USPN 7374499 titled “Golf Club Head with Dual Durometer Face Insert” and describes the invention as:
A golf club head includes a face insert that comprises an insert core made of a relatively hard (high durometer) durable polymer material that is surrounded on at least its rear and side surfaces by an insert shell made of a second softer (lower durometer) polymer material. The insert shell allows the harder insert core to “float” within a cavity in the club head while being surrounded on all sides by the softer insert shell. This arrangement of the insert core and the insert shell thus provides the advantages of a durable impact surface for desirable acoustic feedback while at the same time resulting in desirable feel due to the softer insert shell surrounding the harder insert core.
It appears that this technology is incorporated in the PING i-Series putters.
Congratulations.
