Ethnology of Manihiki and Rakahanga

Figure 50. Triangular tanged adz (C. 2743). a, front: surface has marked longitudinal convexity; blade and butt surfaces continuous without any distinction except at side edges where shoulders formed by inward inclination of butt; blade slightly convex transversely, defined by well-marked side edges; blade width fairly even throughout; sides curve in slightly to cutting edge, more marked on one side; butt more convex transversely than blade; sides rounded off; adz narrows progressively toward c…

Figure 50. Triangular tanged adz (C. 2743). a, front: surface has marked longitudinal convexity; blade and butt surfaces continuous without any distinction except at side edges where shoulders formed by inward inclination of butt; blade slightly convex transversely, defined by well-marked side edges; blade width fairly even throughout; sides curve in slightly to cutting edge, more marked on one side; butt more convex transversely than blade; sides rounded off; adz narrows progressively toward convex poll. b, back: somewhat rounded median edge commences on back of butt, is fairly distinguishable in upper part of blade; in lower part of blade, median edge becomes less distinct and inclines slightly to one side of median line to meet bevel surface; median edge divides back into two postero-lateral surfaces which are convex transversely and meet front at well defined longitudinal edges; front side edges give adz affinity with triangular adz technique and make up for rounded posterior median edge; bevel surface evident, but lower part broken by concave depression which has marred cutting edge; owing to flattening out of median edge, chin curved in outline; upper part of butt slopes upward and forward to meet convex curve of poll. c, right side: front longitudinally convex; back concave; side edge continuous from blade to butt and over poll; butt slopes upward and forward to meet poll edge. d, cross-sections.
