The primary tool of the canoe carver was the adze, often used in conjunction with the maul. The adze was a cross between an axe and a chisel, and was typically chipped or ground from stone. The adze most commonly used by canoe builders was a "D-adze", which gets its name from the combined "D" shape of the adze and the handle. The carver used it like he would a chisel, carefully carving away chunks of wood, but on the same scale as an axe-removing bigger pieces with considerable force and accuracy. This tool was very important to the canoe builder, who used it to remove wood and rough out the form of the vessel.
