Perforator

a prehistoric tool in the form of a pointed stick made of wood or bone. The upper portion is either thickened or shaped into a figure and sometimes has an opening for hanging. During the Stone Age, the perforator was used to make holes for sewing skins; later, it was also used to decorate clay vessels. As the use of iron spread, bone and wood perforators were replaced by the metal awl.
