Thank you. I really thought a 220 grit diamond plate/stone would have removed metal faster, and more of it.
I have a new appreciation for the amount of effort and time it takes to do stuff like this, in addition to the skill of applying pressure and holding an angle in the exact spot to shape a grind that close to the edge with stones. And I stopped short of a performance-grind....so i can't imagine what it takes to shape a performance grind. The cool part about using the plates was I could definitely see the high and low spots along the blade. Now those are mostly removed and it appears to be more uniform.
I could have really used those wooden jigs and big stone wheels the Japanese sharpeners use. lol
I thought about ordering that 80 grit plate from CKTG, then a 120 grit Shapton glass....but then I was like na, from here on i'll only get thin knives that just need a 2k finish sharpening. lol
