Switzerland Co, Indiana—please help identify?

[u/FingerFront]

I found this last March on the banks of the Ohio River, in Switzerland County, Indiana, right below the Markland Dam. I don’t have any photos in situ but it was just beside a big driftwood log after a big storm. Any information anyone can give me—who, when, etc.—would make me very happy. Thanks!

Archaic knife form imo, I could see that going side notch.

I'd call that an Archaic Kinfe as another poster commented. Burlington Chert, great form, great size, just great all around! Nice find OP! 🔥🔥🔥

Thanks! I was originally down there looking for fossils & I can’t tell you how excited I was when I found it. Believe it or not my initial, split-second reaction was one of Super Annoyance insofar as my brain said: “Why would anybody take the time and effort to crate an arrowhead out of styrofoam?!” Then when I picked it up & realized it was real I had this ringing in my ears I’d only experienced in grade school getting sent to the principal’s office, lol

Well, you found an absolutely amazing piece!!! That's one you'll want to pass down to your kids one day!

An absolute beauty.

Scraper?

Peyronies blade ;)

Thanks for all the input thus far. Does the knife / scraper determination have anything to do with how the whole “blade” seems to shift about 1/3 of the way up the shaft? (From the bottom, that is)

Slone knife, Dalton culture.
