Yep, same problem, most of the rocks used to make points aroud here are referred to as "flint". This includes but is not limited to: Talahatta quartzite, quartz cobbles, Tuscaloosa gravel, jasper, Ft Payne, Dover, Bangor, Tennessee River cherts, Coastal Plains chert, Flint River, Buffalo River and Horse Creek chert.
If anyone ever found a point, no matter how crude, that type of stone is refered to as "flint". I have heard all of the above and some imported stone all called that. Bill
