I witnessed one of those supposed stone 'fish hooks' found in 1968 in SE Oklahoma in Pushmataha County in the One Creek Valley area. And it was found 'in context', as it was a village site and other undoubted artifacts were in abundance, it was of the same material as other artifacts, and the knapping style was comparable to other artifacts on the same site. We were told by other folks in the area that it was a fish hook and they had found a few from time to time. My buddy and I were only 14 at the time and had no motivation to plant it and had no clue it was controversial til many years later. I believe it is an item that has been faked, but I don't believe what we found that day was used as a fish hook. Fishing in ancient times in that area was done by fish weirs, traps, poisoning the water to stun the fish, maybe spearing. They were interested in quantity in a short period of time. If for some reason you just wanted to go fishin alone and just catch one or two, a gorge on the end of a line would be better, cause a large fish could easily snap a flint fish hook. I figure it was actually some type of tool, and gut hook would be a good guess. If you could examine these types of artifacts under a microscope for wear use, that might help establish it as a valid sort of tool. And I would NOT buy one as a 'flint fish hook'.
