I'm looking for a stone to get a mirror polish on some of my knife bevels. My current stones are a Beston 500 and a King 1000/6000. I'm reasonably happy with the edge I get with these, the 6000 King leaves a nice shine but I'd love to get that mirror finish I've seen on some of the bevels around, more just for aesthetics than edge improvement.
I'm thinking something maybe around 10000 grit? A budget option that will do the job?
