Does anyone else have any tricks they are willing to share when it comes to restoring a blade to a mirror finish? The only way I know is start with whatever grit is needed, and work my way up to 2000! Are there any sanding wheels that are in the 1000-2000 grit range?

Has anyone ever tried these out?
