There are 25 specimens of the second type. These are characterized by
an asymmetrical triangular form, usually with one gently curving side,
a second more rounded side, and straight or slightly rounded base (Fig.
29). In general they show flat broad flakes at right angles to the
edges with short retouch flakes and usage scars all around. The largest
is 3¾ inches long, and two inches wide, and is made of obsidian (Figs.
30, 31). Another example is 3¾ inches long and 1½ inches wide (Fig.
31). The smallest is 1¾ × 1 inch.

The third group includes 14 examples. The construction of these is
similar to group two, but they are generally thicker, more symmetrical
and usually longer and narrower. The largest is 2½ × 1, the smallest 1½
× ¾ (Fig. 29).
There are in addition 15 broken pieces belonging to one or the other of
the last two categories.
Eleven pieces were classified as flake knives. These are characterized
by manufacture on a flake, with flaking on both faces but only along
one edge. Shape is variable, but the cutting edge is generally curved.
Largest, 2 × 1¾ inches, smallest 1½ × 1 inch.
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.
