lg • l~ J • Cross section: rectangular working area. Edge wear: crushing and step flaking at the tip only. Size range: length, 38 rrm.; width, 33-5 mm. at the tip; and thickness, 18 mm. Special notes: orientation of wear on the working tip suggests that the tool was used with a linear motion. The degree of wear indicated considerable pressure during use. As seen in the illustration (Fig. 9m), this tool is a small chert cobble which has had several percussion flakes struck from it, leaving the bulk of the cobble unmodified. Three parallel flakes were removed from one face. A fourth flake was removed on the opposite face to gain a roughly rectangular working tip. Perforators and gravi specimen (Fig. 90). tools: notched blade fra 1K. One Description: consists of a portion of a bifacially worked blade, with biconvex cross section and possibly a leaf-shaped silhouette. The basal margin is asymmetrical, oriented off perpendicular to the inferred lonq axis. The opposite end terminates in two possibly post-use fractures. One edge has an intentional notch worked into the blade about 34 mm. above the base. Tliis category and the following, for several reasons, have caused niuctr speculation during analysis. Clothing else in the collection sho~,s much similarity, and little comparable material has been noted in the literature survey. Edge angle: 50°. Retouch pattern: multiple types, parallel lateral, and overlapping oval, are present. Retouch orientation: multiple retouches, generally perpendicular to the edge, but with numerous flake scars at a 30° angle, relative to the long axis, and oriented towards the wider end. Edge wear: slight grinding or polish on the shorter edge. Size range: width, 43 mm.; and thickness, 5 mm. Special notes: the tool has an asymmetrical silhouette such that the lateral basal margin angle on one side is 90°, and 105° on the other. The perpendicular edge has discernable wear in the form of polish or grinding, but quartzite from which the tool is made does not show the distinguishing characters. The unworn edge has an intentional indenta- tion or notch 34 mm. above the base. Beyond this, the edge is inset ap- proxima*_ely 2 mm., but parallel to the lower portion of the lateral margin. The basal margin does not appear to have been modified or utilized in any way other than a slight thinning. Several speculative uses have been proposed for this tool: it miylit have been originally an asymmetrical knife with subsequent brew'age. "~' the remaining notch to facili±ate hafting; or perhaps it was the midsec- tion of a larger biface that was modified by reworking an earlier trans- verse fracture, the angled base, and then broken post-use on the wider
