I find it amazing that there was population of "people" that used this as a way of life. Cranking these pieces out daily. When I was a young lad, I used to follow my dad around hunting/looking for arrowheads in the mid west. We found ALOT (in the farmed fields/streams). They are about as sharp hundreds of years later as the day they were made. I wish I had the gumption to try and make a one or a few.
One of these days maybe I will post up a set of pictures of his collection. Illegal in WA, but not in MO (yet!!!!)
