Figure 203.—Adz cross sections of types.

Figure 203.—Adz cross sections of types.

The plain lines denote grinding and the curves chipping. The relationship between Types 1, 2, and 3 is obvious. Type 3 is merely Type 1 ground on all surfaces as intermediate types have shown but better grinding follows, on better shaping by chipping and the butt receives better attention. Type 4 is Type 3 reversed with the back longitudinal edges distinct (4, a) or ground off (4, b). Type V is a distinct type evidently for the purpose of getting a curved cutting edge. The variation V, b, can be derived from a thin quadrangular adz of Type III but as the front longitudinal edges are deliberately ground off to provide a curved cutting edge, it is classed with Type V. The triangular adzes of Type VI have affinity with the adzes of Type I as pointed out. Type VIII in cross section is Type VII reversed. Type VII is distinct from Type VI.
