The hardstone is ground on a riverine rock with the help of water until it has got the desired shape. It is then fixed to a natural grown angled wood with resin and plant fibers. The shape and manufacture of these adzes is similar to those found from the Neolithic Stone Age in Europe. A variety of minerals are used.

Who created the adze?

Dalton adzes are flaked stone tools from Early Archaic Dalton (10,500–10,000 BP/12,000-11,500 cal BP) sites in the central United States. An experimental study on them by U.S. archaeologists Richard Yerkes and Brad Koldehoff found that the Dalton adzes were a new tool form introduced by Dalton.

What is the purpose of an adze?

Adzes were used by woodworkers for cutting and trimming rough wooden planks and shaping and smoothing wooden surfaces. They thus acted both as carving knives and as planes, neither of which was known to the Egyptians.
