WHAT IS THE GRAVER?

A stone tool manufactured from a flake by chipping (pressure flaking) it on two edges at one end so as to leave a sharp point. Gravers were used to cut or score soft materials such as bone, shell, wood, and antler; perhaps also for punching leather and other purposes. The term also refers to a type of metalworking tool that comprises a number of subtypes, though all are handheld, hard, and sharp and are used to cut or engrave metal. Such a graver has a metal shaft that is cut or ground diagonally downward to form a diamond-shaped point at the tip. The angle of the point affects the width and depth of the engraved lines; the point is guided by thumb and forefinger.
