Thanks for the post Cannonman! I agree with you. A lot of times tools are overlooked by collectors. I have a friend of mine who won't keep a drill, scraper, or celt. He will keep a hardstone celt, but that's about it. He was walking a couple of rows over from me one day. He picked up something and then tossed it aside and said "Another dang drill". I stopped and asked him if he was kidding. He said that he only keeps points. After I found and picked up the drill, I asked him to give any others that he found in the future to me. He laughed and said that he would. He's a great guy, but just doesn't care much for tools. I generally keep any that they made, points, blades tools, etc. You can learn a lot about them from their tools.
Good luck!
