Here is a old lightly used hand made single blade knife. The stamp on the butt is FA 53. I didn't get very good pictures of that but it's deep and clear. No blade stamp, doesn't look like there ever was. Handle is old brass cartridge excellent condition, no damage. Closed length 5-1/2 inches. Blade is excellent about 3 inches. Photos show it pretty well. Buyer to pay shipping of 3.95, out of country 18.00 and thanks for looking.
