Do you guys think that dragging a blade across a stone by hand sharpening can possibly raise the edge temp to 3600°F (2000°C) even for a few milliseconds?I guess I can imagine that maybe, possibly, a molecule of steel might freak out and get really hot as it was torn from the edge, but even it that was actually the case, would it be significant?
