Fig. 250.—Perforator, not stemmed, expanding base.
D. Piercer thin and slender; base thin, expanding to a wing-like projection on each side. Very few are strong enough to have been used for drilling even in soft material, but they are excellent for piercing leather or similar substances. The expanding wings would make them good points for hunting and fishing arrows, as they would have great penetrating power and be very difficult to extract from a wound, while allowing very firm attachment to a shaft. The type, shown in [figure 249], is from Kanawha valley. Other specimens come from the same locality, and also from southwestern Illinois, and Brown county in the same state; eastern Tennessee; Keokuk, Iowa; Scioto valley, Ohio; northeastern Kentucky; southern Wisconsin; and Savannah, Georgia.
E. With slight expansion at the base. These may be thick or thin, wide or narrow, and, according to their different forms, might be used as drills, piercers, or arrowheads. A good example (presented in [figure 250]) is from Kanawha valley, West Virginia. It is found also in northeastern Kentucky, northeastern and southeastern Arkansas; eastern Tennessee; southwestern Illinois; and southwestern Wisconsin.
All of the foregoing perforators are without stems, unless the larger portion left at the base may be considered as such.
STEMMED FORMS.
The form of the stem and shoulders among perforators is often the same as in the stemmed arrowheads, etc., previously described.
