In the pre-Craftsman days, Fulton appeared to be the most popular brand offered by the Sears for tools such as saws, axes, planes, chisels, hammers, pliers, and many other items. References to Fulton tools appear in Sears catalogs at least as early as 1908, with illustrations showing either "Fulton" or "Fulton Tool Co." on the tools."
