Watchmakers Round Graver No. 53 marked U.S.

Watchmakers Round Graver No. 53, marked U.S. which I'm presuming is where is was made and not by whom but I'm prepared to be corrected. That said, these are quite clearly hand-made gravers. Comes from the estate of a watchmaker who acquired these while attending the Taus school in N.Y. in the 1940's. Graver is unused and and was never mounted so it does not come with a handle, thus you are only buying the graver. Round Gravers feature a tapered point with straight sides and a rounded tip and are one of the easiest graver shapes to control when cutting using a lathe tool rest. Tool measures about 4.25" long. I likely have several of these so the one you get may differ slightly from the images. Images do a suitable job of representing the item.
