Couple things, first I agree it looks to be an Adena with a little possible base damage. Still a very nice Point and a great way to find one. I think I would hit every bare spot in that soccer field.
Second, I'm not sold on it being Kanawha Flint. It looks to shiny for Kanawha to me and I think it might actually be some Black Coshocton without the usual white inclusions. I don't think it's Zaleski though. Zaleski is much better quality than that material.
