I found the following note about finish honing/polishing so long ago that I’ve forgotten the source. It bothers me that I am unable to attribute the original author of the note.

“ If you are going to be slurry honing on a very hard stone (raising slurry with a hard stone) it's counter-productive to polish the stone too much. It will only make raising a slurry much more difficult. Best is to flatten the stone with a diamond plate then raise a couple consecutive slurries with the rubbing stone and wash them away. Raise the next one and hone with it. This is for finishing only after something like 8k. If you want to try it from a little earlier in the progression you can go to 2k then raise a diamond plate slurry and hone on that, then a rubbing stone slurry and hone on that. Repeat by raising another rubbing stone slurry if necessary until you get your finished edge. On most stones the last one should be a fairly thin slurry, not too thick. Oh, and the radius you have on the corner of the stone should be sufficient. Only polish a very hard stone surface if you are going to use it without slurry. Otherwise you are better off letting the stone go to its natural state during slurry honing.”
