Several pecked marks are noted on the stone adze, with the stone showing clear signs of weathering. Tooling marks are concentrated at the edge of the adze’s blade. A stone blade of an adze is almost always off-centered. Its cross section is shaped like a trapezium. Stone adzes are used for lumbering and shaving wood and logs. According to ethnography, a stone adze is usually fixed to the end of a wooden pole in order to increase its efficiency. The wooden poles do not normally survive but the stone adzes usually remain.
