The tool includes a body portion having an angularly adjustable handle and carrying a pair of cutters mounted to the front wall thereof and projecting downwardly to cut a rug or a pad when the body portion is moved over the top surface of a carpet or pad. The body portion is mounted on rollers and is also provided with an adjustable guide which slides against the wall or baseboard to control the width of the cut being made.
