One large stemmed artifact with straight sides and a blunt point is felt to have been a hafted knife. The base is broken. Estimated length, 2 inches, width 1⅓ inches. The material is quartzite.
For all the categories of cutting implements, approximately 70 percent were made of flinty or crypto-crystalline quartz; a rather large number were of fossilized wood, not commonly used for other artifacts.

SCRAPERS
End Scrapers ([Figs. 32], [33])
The end scrapers are divisible into three categories. The first form is a flat scraper, generally triangular to oval in outline. The working end is often thin. There are a few true snub-nosed scrapers in this category. The second type is generally fan-shaped with a wide thin bit. The opposite end usually tapers to a sharp edge which could have had secondary use as a cutting tool. The third variety includes rougher forms, though there are a few well made specimens. All have a distinct keel. There are 31 of the first type, the smallest ½ × ⁷/₁₆; the largest 1¼ × 1½ inches. Of the second group there are 17 specimens, the smallest 1¼ × ¾; the largest 1½ × 1¼ inches. There are 10 of the third form, the smallest 1 inch square, the largest 2½ × 1½ inches. Seventy percent of the scrapers are of crypto-crystalline quartz.
