Tool or flake?

[autographcollector11]

Found in Illinois. Any characteristics of a certain era? Does it look utilized or worked?

I vote flake. It's so small- and those tiny flea bites along the edge could very well have been caused by being bumped around w/ other rocks. Or could be a view of what remains after knapping away a larger piece w/ sharpening marks. I have lots of flakes w/ tooling marks, but too small to be of any real use. Debutage. HH! Yakker

Is the end broken? I find some worked flakes but the long ones are usually broken in half.

From what I see it's a flake, you are looking hard, that's good
