To make beads, pieces of slate are sectioned into squares using the edge of a hard stone flake as a graving tool. A drill bit of a blade, made of quartz crystal, is used to drill the holes from both sides. The square pieces of slate are snapped off and strung on a rawhide cord. The rough beads are ground to a round shape by grinding and rotating them on an abrading stone.
