I live on a lake and found this small cache of shell tools in my backyard garden along with several pieces of sandstone. Two appear to have been incised, one with tally marks(?). Included is a complete Kirk/Six Mile Creek(?) I found in close association a few months before.
No, it is a very smooth and solid chert. Just the slightest tip nick and a couple small nicks on the side. A little over three inches long. Very nice... and very lucky I didn't hit it with the shovel, Lol.
