without being exact i would call it a lanceolate point, most likely a knife but could be a spear tip, somewhere about paleo or so...lets say, 4 to 8000 years ago.

Awesome I was hoping that would be an answer this was on a creek half mile off the river excited to go back and find more. I know this isn't a certainty but my first paleo find if it is

I'd have to disagree that it's a lanceolate point, maybe a cobbs (8000 - 5000 B.P. -Archaichttp://www.lithicsnet.com/glossary.html#Middle Archaic)
or just an irregular knife form, nice find !

From the shape I would say knife, but it also looks like the one side toward the front of photo has been reworked. It's a nice find

It looks like a well used Adena blade to me
