These seven scrapers were excavated during the 1977 Kansas Archeology Training Program field school at the Tobias site in Rice County. Scrapers such as these would have been hafted on a handle and used to scrape hides. They would have required periodic resharpening. All seven scrapers were made of Alibates agatized dolomite from the Canadian River valley in the Texas panhandle. The Tobias site is a Great Bend aspect (ancestral Wichita) village that had dense artifact deposits, house remains, and numerous deep trash-filled storage pits. The site is listed in the National Register of Historic Places.
