Figure 51. Triangular adz, without tang (C. 2744). a, front: surface slightly convex longitudinally and transversely; lower end shows loss of cutting edge by large chip fractured obliquely downward from before back; sides marked by distinct edges; surface narrows from cutting edge to poll formed by convex curve somewhat lower on one side. b, back: posterior median edge extends from just below poll and meets what was evidently triangular bevel surface at its apex; of bevel surface only trace of upper part remains but is sufficient to indicate that it was triangular; median edge divides back with two transversely convex postero-lateral surfaces which meet front in typical acute angled edges of triangular adzes. c, right side: longitudinal front edge continuous between blade and butt and continuous over poll. d, cross-sections.
