I am looking to get a lower grit stone to do some minor repair on some ebay specials that I want to practice honing on. I have a Norton 1K, but even this is too slow for what I want to do, and the 220 much too coarse than I would like to use.
I am thinking of getting a Shapton 500 glass stone, Naniwa chosera 400 or 600 or a 320 superstone.
I would appreciate any thoughts and suggestions.
