Fig. 5. Components of planilateral axe-adze manufacture from Waim excavations.

(A) Large siliceous argillite preform prepared by grinding all surfaces of a naturally occurring tabular slab, with the distal ends heavily ground to obtain an acute angle. (B) Siliceous argillite with deeply incised cut marks, perhaps delineating the distal end of an axe-adze, demonstrating the use of cutting as a manufacturing technique at Waim.
