[QUOTE=Euclid440;1722281]The 12k Super/Specialty stone, all the stones in that series, are notorious for loading up. Frequent refreshing/resurfacing is needed and will provide a better honing surface and edge.
A diamond plate for doing so, is a good investment. Chef Knives to Go makes a very nice 400/1000 dual grit 8X3 diamond plate for $35.
I agree diamond plates are a good investment. Can't recommend the CKTG plate. I purchased one, and the diamonds are coming off. probably good for sharpening knives. Not good for lapping. Just my experience...
