So a few days ago I was digging in my garden, which is mostly sand underneath the topsoil, and my shovel hit something about a foot and a half down. After bringing it up with my shovel, it looked to be some sort of stone knife, although the very end tip is missing. It fits perfectly in my hand, so I tested it to open some bags of soil conditioner, and the darn thing cut very well! The stone blade looks worked and isn’t like any other rocks I’ve ever seen around here. I also found a roundish, small cutter in the same location, made from the same stone as the blade that also fits perfectly in my hand. Just curious if anybody else out there has run into these kinds of things while digging?
