This is a flat graver for bezel setting cabochons with a diameter of approximately 5.0mm. A commercially available red graver has been shaped and polished. It has not been hardened. The corners have an R (curve). The striking surface is almost flat, so please lightly grind it to an R shape as needed. You can use it as is, but the striking surface will get scratches and roughness with use. We hope that those with knowledge and skills in graver shaping and polishing will consider purchasing it. ★ If you purchase multiple gravers currently on sale, the shipping cost will be reduced. Please specify the graver number, etc., in the comment section before purchasing. We will relist them in a dedicated listing.
