Family patriarch Nordy Rockler opened the doors of his first store in 1954 to supply his fellow craftsmen with knowledge, friendly advice, and a large selection of tools for at-home woodworking projects. Now, the chain of retail outlets brims with more than 20,000 tools and specialized woodworking equipment. Next to a steely rainbow of hinges, casters, and screws, a supply of lumber and exotic hardwoods provides planks for building tree houses or just leaving around as a warning to uncooperative trees. The tenor buzz of power tools operated by newly knowledgeable guests drifts from educational sessions on operating equipment and woodworking.
