Glenn - It's a worked flake tool. The piece is a percussion reduction flake. The bottom of pic 1, right hand corner in slide 2 and the end facing you in slide 3 the struck platform. Then the flake was retouched along the edges and probably served as a flake knife. Cool find. No question to me it's an intentional tool. Being worked on only one side is very common in flake tools like this.
I am sure they are tools that were used. Looks like an end scraper and another little round scraper that I can't id, other than scraper. Great finds. Nice secondary flaking on the piece that you have siting up in your last pic!!
