A leather knife sheath, possibly made from a parfleche, with painted designs.

Most sheaths were made to match the shape of the blade, the most common blade form being curved on one end and straight on the other. The sheaths typically covered not only “the blade but also the majority of the handle,” which decreased the chance of the knife falling out or getting lost (Taylor 2001, 52). Quillwork and beadwork decorated the sheaths, and the designs used often signified the owner (Taylor 2001, 51-54).
