I would say yes based on the fact that I have successfully heat treated a blade that had a rough edge to it. They were situations where the edge turned out to be too soft and had to be retreated. From advice that I was given at the time I needed to cut the heat back on the forge to bring the blade up to temperature slowly and evenly and not to overheat. A little edge quenching and the returning the blade to the fire also helped. Also the method of quenching would also come into play. Marquenching would probably cause less distortion of the edge than a regular quench into warm oil and oil might be a better choice than water if dealing with a sharp(ish) edge. I know that a lot has been writen on these boards about not making the edge no thinner that a dime before quenching and, admittedly, I try to observe that rule but I think a finer edge is not the recipe for dissaster that it's made out to be.
