Interpreting Broken Arrow Points
William E. Engelbrecht · American Antiquity · 2015
This paper compares unnotched triangular arrow point refits (conjoined fragments) with whole points from the Eaton site in New York. The differences between the two samples are significant, suggesting that point typologies based on whole points may be misleading. Refits tended to have greater length to width ratios and lower thickness to length ratios, rendering them less durable. While lack of durability is generally considered to be a negative characteristic of stone points, fragmentation of a projectile in an enemy or hunting prey creates a large internal wound cavity, which is desirable. Also desirable is a point base that makes a cut wide enough to prevent drag on the arrow shaft, but narrow enough to have a good chance of passing through the ribs of the target.
