Thanked: 31No doubt this would save a ton of time! But,its mostly a synthetic edge.
I would at least go to 8k then maybe a tomo slurry to basestone or slurried base stone (light slurries) to get the full Jnat stones affect.
Fun to play with naguras but I only use a tomo now from 8k. Its fast and I get the full effect.

90% of the work is at bevel set so then everything is mostly a synthetic edge unless you use a coticule or similar for everything.
Shave off your synthetic then shave off your next nagura . Is the blade sharper or smoother ? You will learn your stones by shaving after each one.
If you jump from 1 k to a nagura progression it takes a loooong time to replace the 1k edge with the Jnat edge.
A 20k synthetic edge is perfect for most people to shave comfortably but 3 -5 strokes on a dry Jnat finisher can tame that edge if it's a bit wiry .
The closer you get to the ideal edge width (0.4 microns ?) the less you have to do to adjust it to suit.Last edited by onimaru55; 07-15-2023 at 03:46 AM.

That's one I have def been slacking on, shaving after each stone. I'll go back and try that today on the 2 razors I still need to put an edge on. I'll give that a go this time and rotate the edge after each.
I do have a question though, and I don't know if it can really be answered due to how different each stone truly is. My understanding is Botan is around 6k, Tenjyou 8k, and Mejiro 10k, and my tomo I have no idea. With that, wouldn't using Botan after my 8k or 12k Naniwa synth be moving backward? Or is it still considered refining the edge of what a JNAT provides?
I'm starting to understand there are way more variables to the JNAT and different Naguras than I originally thought.

Not to me. I don't need to bevel set on a coitcule to have a coticule edge end up on a razor.
Not sure anyone would believe that really.
To get a particular stones edge to a razor you will need to completly override what is there before calling it that edge. A few strokes will not do it unless its a ridiculously fast stone. We are not really talking about the same thing.
If you are using a different stone to finish and want the effect from it then"just a few strokes" does not really change it much.
How you get to the start of your finisher does make a difference - at least to me.
One stone honing does not yield the same results as a progression of different ones.
So yes, how you get there will change the outcome but going from a tomo slurry then diluting out to water will certainly imprint that stones edge much better than just a few strokes from another.Last edited by stoneandstrop; 07-15-2023 at 07:09 PM.
