This particular tool is called a burin, for boring, cutting and slicing. The back end of the tool is used as a scraper. I collected it at a site called Jerash in Jordan. It was turned up along with thousands of other such tools in the process of plowing the fields of the ancient site.
In 6,000 B. C. the site was settled by people engaged in agriculture, so many such stone tools were needed in the cultivation and harvesting of crops. Houselhold chores such as skinning animals and curing hides also called for many such tools.
This scraper-blade is 3in long (7.5cm) x 1in wide (2.5cm) It weighs 1 oz. (28gm)
