I know what you mean there archer, but there are plenty that get plow damage that could be resharpened. Most of them end up in a coffee can in someones closet, I have hundreds of them, even our ancient friends resharpened their points and reused them. Most of the relics in the pic are knives, and a few spear points, I'll try to post later some points that they used as arrow tips, the bow didnt come around until about the late Woodland time period 2300 - 1800 B.P. atleast thats what I've been told and read.
