A friend of mine (muledeernut here on MM) were out walking behind his house and he found this arrowhead by some grind holes.It's the smallest one we have seen.
that is a small arrow head. It amazws me how they could make something so small and fine like these. I think I have one that is about the same size and one that has got you beat. You have got to have good eyes to pick these out. Do you know what these small arrow heads would be used for?
