Composite Shaft Putter (2019 debut)

The Odyssey Composite Shaft Putter debuted in 2019, according to golfpartnerusa.com, and the change it made was in the shaft rather than the head. Golfpartnerusa.com describes the shaft as a composite of carbon and steel, in place of the steel shaft that golfpartnerusa.com puts at 110 to 120g on a regular putter. The publication reports the composite version as lighter by up to about 75g.

What that weight change is meant to do is where the record leans on golfpartnerusa.com's framing rather than any independent test. The publication reports the feel as firmer than a regular one, allowing users to feel the putt through their hands for a better touch, and credits the shaft with improving consistency in various putting aspects, such as the back swing level, face angle, tempo, and speed. Those are golfpartnerusa.com's characterizations of the shaft's effect, not a verified spec or a house finding, and should be read as one outlet's account of what the composite shaft does rather than an established figure.

Against its own line, this release reads as a shaft story more than a head story. Nothing here describes a particular head shape or finish paired with the composite shaft in 2019, only the shaft's material change and the weight and feel claims that came with it.
