I have great plenty of experience grinding blades and heat treating to pay any attention to overheating steel by sharpening. You have to get a blade 350°F to even come close to tempering it down a point.
I think this is fact- Tool steel must change color to affect the heat treat at all. The color it turns is a very precise temperature gauge.
I have kilns and Rockwell machines, so that is ancient HT history myth busted.
If you're blades are even getting warm, either change to a new belt, or use less pressure.
