I find so much worked rock. The flint here has inclusions in it and they would of chipped many rocks before they found 1 good enough to make something with. I believe that is why I find so many scrapers. Didnt take much talent to make a scraper with the flint here but try to find a well made point. I believe your 2 pieces could of been used but most likely were tossed they just dont look finished to me but could of been used.
