Here is a old used three blade utility knife. The stamp on the main blade is deep and clear but all it has is the patent numbers, USA made. All three have strong snap. Still very nice old knife. Blades show light use, . Closed length 3-3/4 inches. Everything is nice and tight tight open and closed and very solid. Photos show it pretty well. Buyer to pay shipping of 5.95, out of country 18.00 and thanks for looking.
