Hand engravers use a tool called a graver. It is a piece of flat rectangular steel rod with one end sharpened and the other end finished with a rounded wood knob that is cradled in the palm of the hand.
The graver is pushed along the surface of the metal cutting an angled groove. This creates a crisp line that is bright and shiny. Gravers can have different shapes on the cutting end for a variety of decorative techniques. The shank of the graver can also be bent to work on the inside of rings.
Hand engraving is different from other decorative techniques in the sharpness of the lines and its permanence. Rings engraved in the 1500s still have clear designs. Machine engraving cannot cut as deeply as the hand technique. Stamping and etching are not as sharp. Lasers and die cutting can also be used on metal but the results look machined rather than finely crafted.
An engraver's block is used to hold many types of jewelry and silverware for engraving. Pins with different types of heads are inserted the the holes in the split, flat top of the block. The pins are shown slightly enlarged here. The two top halves can be screwed closer together while the pins hold the piece to be engraved.
