Adze

The adze (/ˈædz/; alternative spelling: adz) is a cutting tool shaped somewhat like an axe that dates back to the stone age. It can be any tool with a sharp cutting edge. Adzes are used for smoothing or carving wood in hand woodworking, similar to an axe but with the cutting edge perpendicular to the handle. Two basic forms of an adze are the hand adze, a short handled tool swung with one hand, and a foot adze, a long handled tool capable of powerful swings using both hands, the cutting edge usually striking at foot or shin level. The blade of an adze is set at right angles to the tool's shaft (like a hoe or plane), in contrast to an axe's blade, which is in plane with the shaft. A similar, but blunt, tool used for digging in hard ground is called a mattock.
