This isn't one of those "inspired by" Henrik Stenson Piretti. It was actually USED by him!This very unique and rare putter was confirmed by Bill Craig, General Manager of Piretti Golf, as one of the prototypes made for Stenson that he personally used. This putter has Stenson's initials stamped in the bumper (HS.P, P for prototype) and HSP engraved on the face.The putter carbon steel with a black PVD coating and tri-sole. The finish looks black without light but the PVD finish make...s it very blue under the sun. Has natural patina which I feel adds to the uniqueness of this putter. I would never refinish this. Here are some specs:Neck is .25" longer than standard.360g3* Loft69* Lie35" Long Newly installed Ping PP58 Grip (Tiger's grip).Will come with Piretti Headcover.GolfWRX - smrtchar
