The Material Culture of the Cook Islands (Aitutaki)
What corresponds to the anterior surface of an adze is straight transversely and very slightly convex longitudinally. Posteriorly, there is a well-marked posterior mesial longitudinal edge. To the light of this is another well-marked longitudinal edge formed by the meeting of the planes of two surfaces. On the left, but further from the middle line, there is another more rounded longitudinal edge. The bevel surface is somewhat triangular in shape, straight transversely and slightly convex longitudinally. The surface of the poll is level and well defined by the clean cut margins of the adjoining surfaces. The chisel is polished and there is no shaping or working to form a grip. The anterior surface is not so well polished.
