This may be junk or it may be something cool, I have no idea. It was dug in among a bunch of broken horseshoes in an artillery camp, maybe its a tent stake or something? Any ideas?
Using my WAG methodology, and somewhat based on what it was found with, maybe some sort of a hoof cleaner/scraper? If it is an implement of some sort, maybe it had a wooden handle or grip, with the way it tapers down along the length. Kind of unusual, though. Electrolysis might help with the identification.
