Rocker groovers have been made from cast iron, bronze, brass, aluminum, and possibly zinc. The handles were either wood or cast as one piece with the tool. Like other cement tools, some were identified with a cast number and a pasted-on label which is long gone, leaving us to wonder who the maker was.
