I made about 3 dozen 'disposable' flint knapping pressure flakers. I say they are 'disposable' as they don't have an adjustable tip like a nice tool would. Once they wear out, they are junk. I made the handles several different lengths as a wide variety of people will be at the flint knapping session on Saturday.
