Bone handled 2 blade jack knife.No numbers can be seen on the blades. Blades in good condition. There is a slight crack on the Back side of the handle ~ I had to look at it with a 10X loop to see it, because my eyes are not so good. Approx. Measurements: 3 & 5/16 inches closed and 6 inches with master blade extended. Good springs ~ very quick snap.
