Thread: Help with J-Nat stone

From what I was told, This stone is over 70 years old or move, it weights 480 grams. The surface is really fine, very very smooth like a CF and smoother than my Escher. I think its a very luck buy!
My question is How do I use this stone? I played with it for a while and it left my razor with a mirror finish but the edge wasnt shape, shape , shape. I need more time to figure out this stone.

Q1) what method of honing should I use with this stone for my razors
Q2) I like having a slurry. whats the best slurry stone to get for this stone
Q3) Can I use a DMT D3E 3 extra fine grit diamond plate as a slurry stone for this stone?

What other advise can you J-NAT owner give me

That is a beautiful stone

You know, there are tons of ways to use that on razors.
Some use them only as a finisher, with water or some slurry created by a diamond plate or a Tomo Nagura.
Others use their JNats from everything after the bevel set.

I'm sure others will chime in, but here's what I do on my JNats:

I set the bevel first, on a Chosera 1K.
After that I will raise a Botan slurry on the stone and do circles and x-strokes untill the slurry thickens.
This process is then repeated once more.
I do the same thing on all my Nagura's as sort of a progression up thru the Tenjou, Meijiro and Koma Naguras.

After that the process is again repeated with a Tomo Nagura.
On this one though, I will thin the slurry as I go, and finish on a almost clean and watery stone.
Just the hint of slurry left really.
I keep at it untill the stone is more damp than wet.

This seems to be what works best for me, but like I said, there are tons of ways to use a JNat finisher

Good luck with your new stone!

Question..

In the 3rd pic down and the last pic it looks like there are scratches in the top surface of the stone,, what caused that ????

I stone much have being lapped becaus the marks are not so visible. It doesnt affect the honing process. Up date, I used a 600 grit wet n dry paper to try and produce a slurry and it works well. It produces a nice a tin creamy slurry.
Any suggestion on how i can use this bad boy?

George my advice to you is to put it away and start with a nice synthetic to learn honing.
Going backwards in stone progression with a Jnat at that is a huge undertaking.

Thanks for the advise, I use My Thuringian grey and yellow green, Escher hone, Llyn melynllyn on a regular basis to get my razor shave ready.

Since J-Nat are different, I need tips and pointer on the right way/ method to get the best out my stone.
Thanks

Fist of all there is no right way to use a Jnat, in general use nagura then tomonagura
here a vid I made a while a go how to use that method:
