I was going to purchase a welche stone that was slate and 10000 grit and had a slurry stone that took it to 8000. which i think would be good for upkeep of my already honed razor. my question is can I add a 3000 grit to set the bevel on new razor thin jump tp 8000 grit or is that just way to big of a jump. also im pretty set on the welche slurry slate so what other grits should i think of being a minimum.
