Check what Lee Valley has for sharpening. Leonard Lee, who founded Lee Valley, wrote the definitive book on sharpening, not my words, that is what Sorby chisel maker of the UK said about it. They make some of the best and most expensive chisels and lathe tools in the world. I use diamond stones, diamond and carbide sandpaper, and a felt wheel with honing compound for my sharpening. The diamond stones or hones are Chinese, the sandpaper comes from either Lee Valley or Heleta Industries (used to be Bullit or Bullet) in the the states, and the felt wheel and green honing compound are from Lee Valley although they can be purchased in a lot of places. The green compound is equivalent to 8000 grit and will put a mirror finish on an edge. I'm only satisfied when I'm able to effortlessly shave hair off the back or my hand or forearm.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
