Native Americans use deer brains in tanning to make leather soft and supple. In addition, this tanning method offers a nice smoked smell. The sheath features gray, black, maroon and white size 11 seed beads lazy-stitched in angular designs. The edges are finished with rolled bead edge stitch. The top and straight sides of the sheath are beaded in "River" design. The center of the sheath has a modified "Storm" pattern and the colors are traditional Navajo rug colors. At the top and bottom are Conchos and the back has a belt loop to wear easily.
