IOWA...Here's another one first thoughts was a nebo only because of the thickness but if I found that here in Texas I'd be singing the angy song.Well I'm gonna go ahead and sing it with the base heavily ground Steep beveling and...the dead giveaway is that serrated edge from top to bottom la la la shake your groove thing yea yea!

This angy measures over four inches and I preciate you peeking for sure.Once again I removed restore from the base a filler that made it look a nebo for sure.

Sooo how do you actually tell a Agate basin from angostura ? One really good way is that

Clovis and Agate basin are ground 1/3 the way up outside edges for a more full hafting well that changed with angostura they did not ground as far up with a thicker point they did not have haft the point to the shaft as far up.....that sounds somewhat legit unh with this ancient technology!

Last pic shows the correct order as resharpenings can change that.....

Nebo is out of my area it could be as nebo is thick its widest at mid point lacks being ground as this point has some grinding to it.
