The general method of using the adze is as follows:—The workman stands with one foot upon the wood in the line of the fibre, and thus assists in steadying the work. The long handle of the adze is curved so as to permit of an efficient blow being given, and the tool brought to a stop before the handle strikes any part of the workman’s body; it is caused to stop by the exhaustion of its impact energy in the fibres of wood. The adze is raised by both hands until nearly horizontal, and then not allowed simply to fall, but steadily driven downwards until the curved metal, with its broad and sharp edge, enters near to, if not below the sole of the workman’s shoe, separating a large chip of wood from the mass; the handle is rapidly raised, and the blows are repeated quickly, the workman gradually drawing back his foot until the end flakes of wood are separated. The edge of an adze often is so keen as to cut through a horsehair pressed against it. It is not pleasant to contemplate an error of judgment or an unsteady blow, but practice brings great skill in the use of this tool. The Indian workman uses the adze for producing curved surfaces, and holds the tool so near its head that the hand touches the metal, the blows being delivered chiefly from the elbow.
