| Description | Adze. Wider on cutting edge. Opposite end is thicker. Unifacially chipped. Light stone. Unground adzes may have been used as a hoe for digging and harvesting roots, bulbs and other wild plants. They could also have served as a woodworking tool. They were made from pebbles which were carefully selected for their shape. The cutting edge was created by chipping at either one or both sides to form a sharp edge. The opposite end is usually thicker. Unifacially chipped adzes such as this one are less common than bifacially chipped adzes although the museum collection includes there examples, 13148, 13149 and 13151. This type is associated with the Late Paleolithic Period. However, rough stone tools also appear in Jomon sites in a variety of shapes including axe shaped, triangular and bowtie-shaped forms. Thus this form may be either Late Paleolithic or Jomon Period. |
