I wonder if the Norton rubbing stone would be adequate?
I used a nagura stone and that worked on the Chosera. But I think you have to be careful not to use a stone that is too hard.
I don't have any norton products.
A little off topic, but I use the Norton synthetic nagura on my Naniwa and other waterstones to do the following things:
1. You can use it to adjust the surface texture of the stone, i.e. smooth the surface left by a coarse lapping plate, or roughen the surface if it seems too smooth so that blades skip and chatter. Just scour the surface and corners and then rinse away the grit very thoroughly.
2. You can use it to clean away stains and embedded swarf without resorting to lapping if that isn't needed yet. Same process as above.
3. You can use it to form a coarse, fast cutting slurry. Scour the surface but don't rinse. This will really boost cutting speed (at the expense of fineness).
Don @ SRD recommended no rubbing stone with the superstone.
To be exact, no slurry. he said you should go to a lower grit if you need to. I agree with the Naniwa. It's very and fine and porous. I saw a pic on here of one that probably swelled from water. Using a slurry IMO is probably not a good idea. I'd agree with Don and Lynn on that one.....
I wonder if it's recommended/advisable to use a rubbing stone with the supers just to freshen the surface between lappings? English mentioned that even the super stones get "dirty" quickly and that the rubbing stone quickly refreshes them. I don't think he meant to create a slurry with it?
