Aluminum Grooved Putter

Ray Cook's site describes this release as the first aluminum putter with grooves, pairing an aluminum face with a milled groove pattern. That description comes from raycook.com itself, not from independent testing or verification here, and it should be read as the maker's own claim about its place in putter history rather than an established fact.

The two attributes on record, the aluminum face material and the grooved milling, are the defining features of this particular head. Together they mark this as a departure from a plain-faced aluminum design, with the grooves presumably intended to do something to the ball at impact that a smooth face would not.

Within the broader Ray Cook catalog, this release stands out specifically for that combination and for the firsthand claim attached to it. Readers can weigh the aluminum-and-grooves pairing on its own terms and decide what, if anything, it changes about feel or roll off the face.
