What I have been trying to find out is if light pressure sharpening on my Kally causes any real world "damage" to the blade. I never overheat a blade. Most of the time there is hardly any perceptible background heating at all. Never any sparks!
I'm open to the idea that the on the micro level at the very edge there might be heating, but what does that really mean for gentle sharpening?
Any heating that is generated, at least the way I sharpen, is minimal and short lived.
Considering the temps/time necessary for HT and tempering are far greater than anything that happens when I sharpen a blade, can it rally make a perceptible difference to the blade? If there is some heating at the very edge of the apex, how deep into the blade is affected? Just my gut feeling is that any change to the blade is pretty minimal and mostly surface related.
When the adverse ramification of grinding is discussed, what does this mean? High speed/pressure grinding? Lots of heat? How does this relate to sharpening?
At least we are raising some interesting questions for discussion and testing.
