Bone handles made from bison ribs or vertebral spines (bones in the bison’s hump) along with detached stone blades are found on Plains archaeological sites on the upper Missouri River. The stone blades are set in bison rib or vertebral spines with hide glue.
These knives are faithful recreations of what they looked like when they were used several hundred years ago on the Plains. This knife was used recently to partially butcher a bison and it performed very well.
