I looked at it in your album. It is a typical preform. Many cultures traveled to the Texas hill country to quarry Edwards chert like that. In most cases , it was flaked into a generic blade to lighten the weight in travel. Then it was traded or used . Some became opportunistic knives and were used then resharpened.
Basically, it is an artifact to be finished later.
