This alternately beveled knife was recovered from excavations during the 1977 Kansas Archeology Training Program field school at the Tobias site in Rice County. The knife is made of Smoky Hill silicified chalk, a good quality knapping material that is exposed in linear beds in northwestern Kansas and southeastern Nebraska. Repeated sharpening on the knife's alternate sides created the bevels. 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.

Date: 1400-1600 CE
