What is Hand drill (hieroglyph)?

The Hand drill is a hieroglyph, , used in ancient Egypt from the earliest dynasties. As a hieroglyph, it can also be used as a determinative for words related to the profession of vase, bowl, pot-making, etc., typically from fine-grained, colorful rare stone, for example unguent jars. The size of drills was small-to-large, small for small unguent jars, and large for more massive, grain-storing pottery. The original jars found in tombs were more often used for ceremonial usages, presumably the reason they are found as grave goods or tomb offerings.
