Flake or tool? see pics

[autographcollector11]

This looks to be a flake w/some wear/utilization.
Based on the pics, does this look like debitage or actually used for something? I am trying to learn the signs between actual use and damage from percussion or wear/tear....
I am showing both sides....
Thanks

From what I see from your photo it has been used for a tool of some sort. One edge has been pressure flaked for some reason, but remember a flake gets no sharper than when it is first knocked off, then after some use you will have to put an edge on it.

Thanks-
What would they use to sharpen the piece? Being a flake, it must be small I assume.
Also, does this edge ever occur as a result of cutting or is it first flaked then used to cut?

That's a nice little utilized flake!

The first edge on the flake would have naturally been very sharp with no chipping evident.. The little edge work you see is the result of re-sharpening the edge as it dulled.

Antler tine was often used to flake or sharpen the edges.
