An adze (ædz) or adz is an ancient and versatile cutting tool similar to an axe but with the cutting edge perpendicular to the handle rather than parallel. Adzes have been used since the Stone Age. They are used for smoothing or carving wood in hand woodworking, and as a hoe for agriculture and horticulture. Two basic forms of an adze are the hand adze (short hoe)—a short-handled tool swung with one hand—and the foot adze (hoe)—a long-handled tool capable of powerful swings using both hands, the cutting edge usually striking at foot or shin level. A similar tool is called a mattock, which differs by having two blades, one perpendicular to the handle and one parallel.
The adze is depicted in ancient Egyptian art from the Old Kingdom onward. Originally the adze blades were made of stone, but already in the Predynastic Period copper adzes had all but replaced those made of flint. Stone blades were fastened to the handle by tying and early bronze blades continued this simple construction. It was not until the later bronze age that the handle passes through an eye at the top of the blade. Examples of Egyptian adzes can be found in museums and on the Petrie Museum website.
A depiction of an adze was also used as a hieroglyph, representing the consonants stp, "chosen", and used as: ...Pharaoh XX, chosen of God/Goddess YY...
The ahnetjer (Manuel de Codage transliteration: aH-nTr) depicted as an adze-like instrument, was used in the Opening of the Mouth ceremony, intended to convey power over their senses to statues and mummies. It was apparently the foreleg of a freshly sacrificed bull or cow with which the mouth was touched.
As Iron Age technology moved south into Africa with migrating ancient Egyptians, they carried their technology with them, including adzes. To this day, iron adzes are used all over rural Africa for various purposes - from digging pit latrines, and chopping firewood, to tilling crop fields - whether they are of maize (corn), coffee, tea, pyrethrum, beans, millet, yams or a plethora of other cash and subsistence crops.
