I have not been knapping very long, I started, got frustrated then started reading some books and started again, things became more clear. I have been knapping on and off for less than a year. Here are a few points I was able to make sitting in a hotel in Dallas, back in January. No real style of point tried for, I just let the stone be what it wanted.
As you can see the point on the right has something in it. I have no idea what it might be, the Black and Tan stone as I call it came from AL, it may be Gold!!!
Other flakes I removed had small pieces in it also. Looks kinda like solder, but can not be scraped out with finger nail.
