Did you see the sharpener I talk about in my OP…? If you can heat up an edge with that or a normal whetstone to the point it loses its temper (I don’t believe it would be possible), you are doing EVERYTHING wrong.
Now if you’re using a motorized belt and just dropping one spot of the blade on it and mashing it down, then yeah you probably could fuck up a knife with a quickness… but only you are that special bud.
Alto still uses differential heat treats on his blades, so he’s not really up on the latest metallurgical science. He’s an artist and a fine craftsman and I appreciate that, but he’s not the ultimate authority on the subject.
I use my belt sander to sharpen my knives now. Also, I only go parallel with the blade. Follow it up with a nice ceramic rundown to clean up the micro-burrs. I can perform surgery with some of my blades now
