I got a new set diamond plates for my KME. I think I wore the first set out faster than I should have using to much pressure. I have sharpened a lot of knives with them, and did my share of reprofiling. Still think they could have lasted longer though. So other than using less pressure, do you have any suggestions? I clean them with a toothbrush and dish soap every once in a while. Couple drops of water on the stone to keep it wet when sharpening.
