The Indus Civilization c8.32

c8.32

Whetstones are by no means so common in the Indus valley as they are, for example, in Sumer, and it is difficult to understand how the edges of tools and implements were kept in proper order. Possibly bricks were used for sharpening tools, for the few hones that have been found are not particularly well made and are mostly of slate, though sandstone specimens exist. The ends and edges of some of the whetstones suggest that they were more often employed to polish metal than to sharpen an edge.
