Edge work question on find

[autographcollector11]

Hi all
If you were to find this on a site, would you consider this a utilized flake or natural flaking? I know that some of these are hard to distinguish, but what's your 2 cents on these?

Looks like a worked edge to me.

utilized flake.Good eye. We called them expediant expendables. Used once or twice when working then ditched.
