A strip made up of a linear series of rigid links hinged together. Magnets are mounted on certain links, at spaced points, for holding the strip on the object to be cut by a torch. Spacers are located on the links on which the magnets are not mounted, holding those links in spaced relation from the object, even with the other links. All the links together define straight lines of their side edges.
