WHAT IS THE BURIN ?

BURIN: A specialized engraving tool with a chipped flint or stone shaft that was cut or ground diagonally downward to form a diamond-shaped point at the tip. The angle of the point affected the width and depth of the engraved lines. The shaft of the tool was fixed in a flat handle that could be held close to the working surface. A burin had a wide rounded end for bracing against the palm of the hand and the point was guided by the thumb and forefinger. A blade or flake could be formed into any one of about 20 varieties of the tool. In its most characteristic form, the working tip was a narrow transverse edge formed by the intersection of two flake scars produced by striking at an angle to the main axis of the blade. Sometimes one facet was made by simply snapping the blade, or by truncating it with a steep retouch. Burins were used to carve or engrave softer materials such as antler, bone, ivory, metal, or wood. This tool was characteristic of the Upper Paleolithic (especially Magdalenian) in the Old World and of some Early Lithic and Mesolithic cultures of the New World. [graver]
