    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?

    A smooth shave ready razors edge every time.

    Unbelievably boring really.

    The observation I would make is that the Chosera is a harder stone than the Superstone. This said, the Chosera is a much softer hone than I am used to and the Superstones are very soft.

    All three grits get "dirty" very quickly and the rubbing stone cleans them back to new again very quickly.

    As to the life of the hones. Well, they are not like a coticule. They release the surface very easily because they are so soft. This combined with the need to clean them with a surface releasing rubbing stone, means the surface is breaking down quite quickly relative to a harder stone.

    So I think a professional will find the hone will not last as long as say a Chinese 12k but the stone hones like grease lightning. Time is money. Naniwa knows that and has priced the stones accordingly.

    I hope that helps explain some of the differences.
    I have about 1000 razors done so far on the Super Stones and no sign of wearing out yet. They get used and lapped virtually every day.

    Boring........yeah, whatever. I am fond of a "smooth shave ready razors edge every time".

    Have fun,

    Lynn
