B. Floor saw, as identified by Bruce Cynar, Leo, Ind.; Albert Ching, Storrs, Conn.; Thad Heimburg, East Aurora, N.Y.; Neil Gaarder, Elk River, Minn.; Frank Scheibert; George Wanamaker and Buck and Cathy Evans. "The curved blade allows you to cut into an existing wood floor without having to dismantle the floor or remove boards," Bruce says. From Albert: "The saw allows the user to use a rotary motion to make an initial cut through the flooring which may then permit the use of a conventional hand saw to finish the job."
