Definizione

• Jeweler's Saw.  A hand saw intended to use on small objects of fine metal. Like a coping saw with a wide yoke it has saw blades of several kinds intended for narrow cutting: flat blades for straight cutting and circular blades for cutting in any direction, as around detail. The blades range in width from 0.0063 to 0.0236 inches (sizes 8/0 to 14). Jeweler's saws are used in the medallic field to trim silhouette items or to cut out openwork areas by hand, to make cutout items of existing coins and medals, or to cut INLAY inserts.
  An example is a medal struck by the United States Mint, Saint Clement's Hall Medal, 1874 (RF-19), was struck and delivered untrimmed. The small quantity (3 gold, 8 silver, 24 bronze) were trimmed outside the mint by a jeweler using a jeweler's saw. Such hand trimming is less expensive than having a tool and diemaker create a trimming tool unique to this shape and to trim these few pieces in a press. The edge is then made smooth by abrasion and polishing.
