Or farm had a field where we found a lot of arrowheads, Mostly scrapers and chips from making them. Most were small bird points but my sister found a spear point. I don't know what she did with it because she just didn't want me to have it. I also once found a piece of sandstone with a groove in it for shaping arrow shafts. The odd part was there were no rocks of any kind on our farm. The flint had to have come from the flint hills about forty miles to the east.
