Can someone please elaborate, or point me in the direction of an already established thread about the differences between a pre-finisher, finisher, and polishing hone? Why the need to polish - is there a notable difference in the edge performance, or is it just for aesthetics? Is a pre-finisher different than a higher grit bevel setter? I know grit ranges are hard to say, but is there a grit range difference between these. Also, bonus points for an example of a hone or two for each type.

Thanks!
