Potenza 2 Black Onyx Putter

The Piretti Potenza 2 Black Onyx is a blade putter built on the Potenza 2 head, finished in what the maker's page lists as a black onyx finish over a 303 stainless steel face. That face carries a fine milled face pattern, per the same source.

The head is fitted with a plumbers neck and, according to the maker's page, is built with a full shaft of offset for optimal toe hang, placing this release toward the toe-hang end of the blade spectrum rather than a face-balanced setup. Head weight is listed at 365 g.

Within the Potenza 2 line, the Black Onyx edition distinguishes itself by finish and name alone in what we hold on record here. The construction details, plumbers neck, milled face, toe-hang geometry, are the maker's own figures for this specific version, and the reader weighing it against other Potenza 2 finishes should look to those specs directly.
