What would be the best 1k or close ceramic stone to set a bevel. I currently have the king 1k/6k combo stone. The 6k works well but the 1k doesn't work too well. Can't really get a razor to even shave off of it. And after about 15-20 min on the stone it needs to be relapped. I think the problem is it gets unlevel too quick to get a bevel set right. I know there are good 1k stones that are not ceramic. I am just wanting specifically a ceramic stone.
