I'm starting to getting to grips with this Nakayama 5+ stone and the Nagura also cut from a very fine Nakayama, both were kindly gifted to me by a good friend from Japan, the edges are nice the one thing I'm not keen on is the faffing about with slurry and dilution plus the fact that naturals are much slower than synthetics.

But the smoothness that a natural brings out, is well worth the extra time and effort.
I find the synthetics to be a bit too crisp, for my liking.
Maybe try a full synthetic progression, then go back to the natural for a final finishing. Should only take an additional 5-10 minutes, in honingMike

Thanked: 552Agree.
I don’t have a lot of stones, but seem to have found the combination that makes me happy and gives me good 2 or 3 pass shaves.
My most often used progression is a 1k Shapton Kuromaku ceramic to set the bevel, Norton 4K/8K and then a coticule. Final polish is on a Vermio or OOzuku. Touch ups are on the coticule and CrOx on balsa.
HAD has not kicked in yet, except for 3 combination bbw/coticules.David

+1 What Steve said! I have one too! I got rid of my 20k almost two years ago after much testing. I now have two finer and smother than the 20k. The two are Hatatoshi's.

Well this has been quite interesting. I’ve tried 4 fast jnats, and TL;DR, the jnats erase N12k finish a LOT faster than N12k erases jnat finish.
I finished a razor to mirror finish on the N12k before finishing on each of the jnats, then slurried each of the 4 stones below with a worn 1200 Atoma to generate a light slurry. All 4 of them completely removed the N12k finish to the edge in 6 strokes. I have to conclude that it doesn’t take much to remove 12k scratches. This is the first time that I’ve done this from 12k, usually I try them after 1k to kind of judge the speed. All of these stones are blazing fast, and all can make an edge equal to or smoother than the Gok 20k (which I also have).
Between jnats, I went back to refresh the N12k finish and it took many more strokes to do that. Frequently de-glazing the N12k with a worn diamond plate or a piece of King 1k helped immensely with the N12k cutting speed.
So there ya have it.My doorstop is a Nakayama

So you have a string of unicorns. Congratulations !
I once had the option to buy a Nakayama Suita that polished down to 1k but I didn't find the edge as nice as a dedicated final polisher.
I'll still argue those stones are the exception to the rule & don't forget slurry contains different sized particles which causes light to diffract at different angles so what you see as "removed" scratches can be a trick of the eye.
Do the same test with water alone & also shave test. If you have a good microscope would be cool to see the different patterns.“The white gleam of swords, not the black ink of books, clears doubts and uncertainties and bleak outlooks.”
