Looking good. Make an ax, a lot of preforms got used as tools. They may look unfinished today, as far as the maker was concerned, he had the tool he wanted for the job he had to do. Those "preforms" were ax heads, hoes, shovels, scrapers. Hafting it and using it to clean a deer is a great idea. And looking at your points in the background, you are getting good. Don't worry, if you keep hitting rocks, thinness will come. The more you hit, the thinner you will get them. Bill
