If your jnat is slower than your synth, you don’t have the right jnat - yet, lol. That’s OK though, the main job of any final finisher is to make the feel of the edge IMO.

Unicorns may exist but I've yet to see a Jnat that can finish a 12k edge edge in 5-6 strokes like a Gok 20k.

Maybe, I’ll have to give one that I have in mind a try. It will erase 1k Chosera marks over half the bevel with 30 regular razor strokes on it’s own slurry. It will be a fun to see what it can do.

+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.

You are probably not well versed in the matter. The main goal of the finish line is to get a subtle result. It has nothing to do with speed. Speed doesn't matter at all. Where are you a hurry?

Your example of Suita - is another matter. Suita are aggressive stones, they can be very productive, but subtlety suffers.

And more. The work of the stone depends on the size and number of grains, the type of bond, the type of grain. Stone is adjusted for the task and the task for finish razors - get a thin edge. Desirable in a comfortable way. With pleasure. Without haste. Jnat fit this well.

[QUOTE=Sandr;1919943]You are probably not well versed in the matter. What! Lol!
That quote made me Lol! He just does not have the experience that some do. Just because you make razors does not mean you know how to get the best edges. Like someone that makes guns does not mean that they are the best most accurate shooter. Lol!

I do not want to argue. But a specialist cannot write such stupid things about the finish of razor. And compare synthetics with naturals. They are different. The main in the finish - not speed.

Lol! I stand by my quote!

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.

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.
