In 1957 Alum-Screen Patio & Manufacturing, Inc., made the Porta-Saw miter saw and Safe-Guard double miter saw. As the company name implies, these saws were originally developed for cutting non-ferrous metals, though according to the manufacturer they could also be used to cut plastics, plastic laminates and wood.
