Doing some more katsuramuki and I realize I haven't tried many different edge finishers for my watanabe usuba. I've almost exclusively used a hideriyama and am wondering if there's something better? The hideriyama is roughly 9k with considerable bite for that level of finish. I could use a harder stone like a meara (super hard, 5k ish) or an okudo suita (hard, 5k ish), a kitayama synth (8k, smoother edge with almost no bite), a ohira suita (a little harder than hirderiyama but also a little coarser edge feel, 7k ish w/ more bite). I could strop after the stone.... what do people here recommend/use? If total smoothness is the goal, I should probably try the kitayama synth. I wanted to ask before trying these out myself because results with jnats always very and depending on what it was sharpened on before since I only ever do light touch ups and etc etc -->What's the optimal edge for katsuramuki? and what stones or qualities in stones / strops do you look for to achieve this edge?
