Found in kearny county, KS.

Do you think it was local?

Welcome from west central Florida...Looks like a well used knife..

[smbore]

I'd agree with hal.

Its made of quartzite. I agree nice knife form. No way to pin donw a time period for a single find like this. If you had other artifacts which had diagnostic features from the same location you might be able to narrow down a time period.
