VOCABULARY TERM: BURIN

All kinds of engraving is accomplished with the engraver's basic tool, the burin, also called a “graver.” A shaft of steel is sharpened at the end in one of a dozen diamond shapes to cut different shapes. The shaft is inserted in a wooden handle, also of different shapes to suit the engraver's hand. Dies are also cut with other tools.

Burin. An engraving tool with a diamond or lozenge shaped cutting edge, often used for engraving lines, lettering or fine detail in dies. Burins are made of tempered steel with an oblique cutting edge shaped in such a way that light pressure cuts a thin line, heavier pressure cuts a wider and deeper channel. The flared cutting edge also has the advantage in that any cut made in a die has an automatic BEVEL, necessary for any striking work (the die can strike and withdraw without the piece "hanging up"). A burin is also frequently used for INSCRIBING a medal after it has been struck, burins are used for script style lettering requiring narrow strokes and wide stems. Burins are also called lozenge or diamond point graver. See GRAVER, ENGRAVING.
