Maybe these chipped tools will help you. The best thing I can tell you is to watch someone flintknapp or go on youtube and watch a viedo and pay close attention to flake scars. There are all types of flaking, but once you notice what was made by man, then you will see the differences of natural flaking from rolling down a hill or in a water way. The very best thing you can do is spend $30 on a knapping kit and try your hand at knapping. It will give you a better understanding of how these items where made and it will train your eyes to spot flake pattern s while hunting artifacts. Good Luck
