Safe to use pot that has a scratch inside?
I think this is the inside of a non-stick pan, on the side near where the handle is riveted (scratched rivet at the right of the picture).  

It doesn't look like it's peeling from the scratches.  So the amount of coating getting into the food would be miniscule. Even the if it did peel, the result would be more unpleasant than dangerous (paper on the use of PTFE as an inert bulking agent for food); the main component of a Teflon non-stick coating is PTFE.
