This Undercut Beveler Stamp is a great way to lift petals. Stamped on the tool is "US Stamps" and "BW20". The tool measures almost 3/16" in width. We're not sure what type of metal this stamp is made of but a magnet is not attracted to it. It produces a nice, crisp impression and would be a great addition to any leather carver's set of tools. This stamp should not be struck with a weighted maul.
