Nice point, Mike. Here in western NC we find a lot of little Mississippian-phase points. They're just tiny sharp triangles of chert that would fit on a dime. I assume that they were used to kill deer, bears, and people, since that seems to be about the only point type from that time period, and the mounds from that phase are full of deer and bear bones. The stockaded village sites indicate taht it was a time of war, too. It's a long way from here to a source of good stone for knapping, so it makes sense to maximize number of points per pound of raw material.
