Kuchar Arm Lock KM1

The Kuchar Model 1 Arm Lock is the long-shafted version of Bettinardi's KM1, built as a heel toe weighted, face balanced putter with a wider profile. The maker's page describes the Arm Lock as featuring "a double bend shaft with 2.5 shaft offset," a departure from the standard KM1's single shaft offset, and it carries the same patented F.I.T. face treatment, which the maker states "removes 55% of material from the face resulting in a remarkably soft feel at impact." Per the maker's own listing, this version is spec'd at 400G, 7° loft, 71° lie, and a 42 inch length, with a gray 19" Lamkin grip and Kuchar Signature White/Blue headcover, milled from what the maker calls proprietary Soft Carbon steel and finished in Pewter PVD.

Golfshake's reporting on the Arm Lock largely echoes the maker's own language, crediting the design to "Matt Kuchar and Bob Bettinardi," and repeating the F.I.T. face and Pewter P.V.D. finish, along with the double bend, 2.5 shaft offset. Golfshake's coverage also lists a Meridian Blue finish and puts the putter at £279, figures not found on the maker's own product page for this release and worth treating as the outlet's own reporting rather than confirmed spec.

Within the KM1 line, the Arm Lock sits as the alternative-length sibling to the Standard model. Both share the heel toe weighted, face balanced profile and the F.I.T. face, but where the Standard is built at 35 inches with a 1 shaft offset and 3° of loft, the Arm Lock stretches to 42 inches with the double bend neck, 2.5 offset, and a notably higher 7° loft, changes suited to the arm lock stroke rather than a conventional putting motion.
