Interesting flake/tool-any ideas?

What makes this one different if the extreme smoothness on one side of the flake. It looks as if it was worn smooth by something. Does anything that you know cause this type of wear? Could be water worn too I guess...
thanks

One side of a flake is often smooth. It hasn't been struck on the side that was still attached.:-)
The flake comes off smooth with most good material.

Looks like a nice little scraper to me!

That really smooth spot is just the way the flint fractured. I find flakes like that all the time.
