These two scrapers were recovered from the surface of an archeological workshop site near the Saline River in Trego County during the 1997 Kansas Archeology Training Program field school. The scraper on the left is made of a chert called Smoky Hill silicified chalk, while the chert of the right scraper is unidentified. They would have likely been hafted on a handle and used to scrape hides. The tools would have required periodic resharpening.
