These four alternately beveled knives were recovered from excavations in 1966 at the Lewis site in Pawnee County by Kansas Historical Society archeologists. Repeated sharpening on the knife's alternate sides created the bevels. Three of the knives are made of Smoky Hill silicified chalk, a good quality knapping material that is exposed in linear beds in northwestern Kansas and western Nebraska. The fourth knife is made of Alibates agatized dolomite from the Canadian River valley in the Texas panhandle. The Lewis site is multiple occupation habitation site with Pratt Complex (Middle Ceramic period), Smoky Hill aspect (Middle Ceramic period), and Great Bend aspect (Late Ceramic period) occupations.
