}}Sharpening a graver or burin requires either a [[sharpening stone]] or wheel. Harder carbide and steel gravers require diamond-grade sharpening wheels; these gravers can be polished to a mirror finish using a ceramic or cast iron lap, which is essential in creating bright cuts. Several low-speed, reversible sharpening systems made specifically for hand engravers are available that reduce sharpening time. Fixtures that secure the tool in place at certain angles and geometries are also available to take the guesswork from sharpening to produce accurate points. Very few master engravers exist today who rely solely on "feel" and muscle memory to sharpen tools. These master engravers typically worked for many years as an apprentice, most often learning techniques decades before modern machinery was available for hand engravers. These engravers typically trained in such countries as Italy and Belgium, where hand engraving has a rich and long heritage of masters.
