What is this?

I know nothing about Indian artifacts. Found this on the edge of a creek. Someone said it's part of a knife blade. Is it part of a knife blade or spear point? Thanks

Also found a harpoon point. Haha

Not enough there to make any kind of identification, possibly a blade.

It's part of a mid-stage preform that broke in manufacture. I find lots of them in places that I'm gathering rock. Here's one that they never finished. It's got super heavy creek patina.
