This opener entered the marketplace in 1954. It was originally sold by the now defunct U.S. Swing A Way company. Some of these openers are still working 40 years on. They are made from carbon steel, feature skip proof feed wheels and are gear driven. The cutter, gears and wheel are all heat treated and zinc plated. Newer, thicker and more comfortable pads have been added. This is the very same albeit slightly better great can opener. Nothing compromised. No shortcuts. Do not wash, rinse, soak or put this opener in the dishwasher. It is made of carbon steel. Simply use a cloth or paper towel dipped in vinegar or hot soapy water to wipe the cutter wheel and gears clean.
