A graver made and used by Roy Cooney. A wooden handle with a steel rod fitted into a groove on the underside of the handle, held in place by twine. This graver has a lozenge-shaped end, and was used for cutting lines of various widths. It could be sharpened to give a very fine line, or ground along the lower edge to give a broader line. Broader lines would be used for features requiring particular emphasis, and the body-strokes of lettering. The lozenge-section graver could also have its lower edge rounded, for use cutting intricate bends in coastlines or rivers without creating too much burr (raised bits of copper on the plate which can be produced while engraving).
