This rasp was excavated from the Crandall site in Rice County during the 1983 Kansas Archeology Training Program field school. The rasp was made by cutting grooves into a bison rib. At some point, the rasp was broken into two pieces. Archeologists believe that artifacts like these could have been used as musical instruments by drawing a stick across the grooves. The Crandall site is a Little River focus Great Bend aspect (ancestral Wichita) habitation site.
