Thread: slurry stones vs surface stones and what is this jnatism?

I use JNAT slurry on Charnley Forest and result is very good. Side effect is better surface on my CF after sharpening with slurry. So JNAT slurry interacts with CF.

At the suggestion of a member very wise and experienced I used a nagura to create a thick slurry on my 8k Norton. The secret was in the mud! I appreciate his suggestion and thought I'd pass it on here for others to follow. Thanks Glen!!!

About midway through the thread you'll find where I used an Arkansas stone and some Western rocks to form a Jnat style progression. The hard part was finding something for the 4k and below range because as far as naturals go, it seems here in the West we mostly covet fine finishers and don't dig up much in the low range. Slurry size stones are also somewhat unusual, but can be found if you look about. You can do a lot with a piece of coticule and an Arkie. Or you can cheat and use a piece of coarse Naniwa stone for low end grunt work.

At the end of the day rocks are rocks. You can get a similar result from Western stones, and if you dug in the right area could probably find suitable sedimentary stones to mirror them to the letter. The real difference I think, is that they have continued to mine and sell them, while by and large we've moved beyond traditional sharpening means to primarily synthetic stones for the low and mid range while keeping a select few natural stones around that are good for making the final polish.

" You can do a lot with a piece of coticule and an Arkie."

I just discovered the pleasures of coticule slurry on other stones. What an eye opener! My run in Washita was getting a bit slow during bevel set, my hardest coarsest coticule to the rescue. The accidental, recalcitrant slate I got instead of the black Ark I thought it was, is now my most useful prefinish due to the addition of a little soft yellow coti slurry. I was sure it was a dud before this. The coticule slurry seems to interact with the slate during honing causing it to release a little of it's own slurry also. The results are simply stunning. I was going to get rid of this stone before this. Must experiment more!

If you don't try jnats then you will never know.
Eschers are special too.

i thank you all very much for your insights. very helpfull for me!

have a good one
