Hi, found this yesterday at the end of my drive. . Edge is relatively sharp. Wondering if it might be an artifact of just a neat rock. Thanks for looking. -Mike
I can't see a lot with the one pic. it reminds me of this hammer that my dad found years ago. Some tell me it's natural, but I find that hard to believe. The stone makes a "tink tink" sound like metal when you thump it. The business end shows a crack from pounding and the river patina appearance it has isn't river patina. I'll post a few for comparison. I may be far off the right answer, but here is my attempt to help.
I hope this helps, even if it only allows you to eliminate one possibility.
I have only one more pic right now. It is not a good angle. I can take some more pics Monday as I left it on my desk at the office.
