I found this when I was looking to see what they are used for...guess it had many uses! :0) "Bone awls or perforators are found at most archaeological sites and were in use throughout all prehistoric periods. They were used for punching holes in skins or leather for sewing garments or other articles of clothing. Bone awls could be used for perforating most softer materials and many of them were probably also used in the manufacture of basketry, matting, or similar woven materials. As a consequence of usage, the awls became highly polished, not only from handling the awl but from contact with the working material."
