Thanks for the continued responses guys. A chisel or tent spike seems fairly likely due to the size. I didn't include the size like I should, but if it was a prybar/crowbar it would be the smallest I have ever seen. In regards to finding things similar to tent stakes I haven't found much. The artifact scatter at the site seems to be completely random with nails being the most common along with pottery. So much iron that discriminating doesn't do much.
