As a knapper I might see things a little different than standard thinking. I’m not sure why some assume that certain cultures only made one style of point. I’ve worked material that is almost impossible to flute so instead make another style point, both being used for the same purpose. Here in west TX we see allot of Plainview, Yuma style points but from time to time fluted points are found. I really like the Hell Gap style point because it’s a great representation of a transition maybe not from a certain period but simply because of the material. With lets say gem quality chert I have a pretty good success ration with fluting points. Lower that quality of material and that ratio goes way down. So instead of coming from the end to thin the point down I have to come in from the sides creating a completely different style point. I know I’m not doing a good job of explaining myself here but I guess I’m trying to say that for one culture to make several style points just doesn’t sound unreasonable to me. The Clovis and the Solutreans made a wide variety of points and tools.

Absolutely... I have done a little playing at Knapping and understand completely what you are explaining with all this. And then there is the difference between stone that works better after heat treating and stone that will work well without heat treating. It all boils down to what is available and how it will work and shape has to be adapted to best use what is available.
