Two artifacts are designated spoke-shaves. One is combined with a perforator; the other is made from a large flake. Both exhibit simple steep flaking. The working surfaces are arcs of about 100° on small circles, ½ inch in diameter.
Drills ([Fig. 38])
Though only five specimens were recovered that can be classified as drills, they comprise four types. The first, represented by one specimen, is of the expanding base T-shaped variety. The base is flattened and the point is diamond-shaped in cross-section; the flakes were struck from either side to meet in the middle and form the central ridge. The second type, possibly a variant of the first, comprises two specimens, one fragmentary. The bases expand but are thick and irregular, rather than flat. The point of the complete example is biconvex to diamond-shaped in cross-section and exhibits fine workmanship. The third type differs from the first two in having a straight base. It is biconvex in cross-section, with rather fine flaking meeting along the midline. The fourth variety has the outline of a small side-notched projectile point. Upon examination, however, the edges of the lower one-third of the point show signs of extensive abrasion and polishing. It is very probable that such a tool was hafted for use. The method of usage is less certain for the others. All five were made from varieties of flinty quartz.
