Ok, so I was using a buffing wheel for the first full on attempt to save a stained blade without hours of handsanding. I got a little aggressive maybe. It was a pretty flexy blade before hand. Are there other tell tale signs besides blueing that I've lost temper? It just happened once, but it got HOT...that one time. Not enough to burn my skin, but hot enough to make me snap my hand back...Thoughts? No blueing occurred.
