Thread: Question about 10000 JNat and personal conclusions

Hey Folks

I just sharpened my Dovo 5/8
I got some diffent stones out, and made a comparison
(finish with just water!)
1. King 8000 (artificial Al Ox)
2. A Jnat (dont know the name, hard, light with red hue on sides, supposed to be 10000
3. A Coticule (8000) La Grosse Jaune, nice big piece

Under my lens (10X)

I noticed

1. Nice shiny polish but some very noticable scratches
2. Less shiny then the Coticule and King but very even pattern! very smooth pattern, not scratchy at all
3. Nice shiny polish but alot of noticable scatches

I Always finish with Crox, sorry I just like it sharp. This is a bit backed up by some info that CroX is 30.000

Are my conclusions right that this Jnats is slow, clowdy but very consistent and not scratchy and thus in combo with Crox is a better choice then the much faster King and the faster Coticule

So my question is, are my conclusions correct?

First things first, JNats are meant to be used with a slurry. When used with water yes they are very slow. Used with slurry they are quite fast indeed. If you get your honing dialed in you shouldn't need paste to get a keen comfortable shaving edge using JNat or coticule. I have no experience with the King 8k.

@Ekretz
Thank You !
I started the Jnat prog with slurry and ended with none.

Well I hope one day I will get my sharpening dailed in.....no comfy shaves here without crox (cries...)
But I might give the final polish with water and no pressure maybe like 10 minutes more Time. (coticule)

Coticule edges very rarely look polished in my experience, but when they are done right they give a quite comfortable shave. Some cotis are tougher than others - the softer ones especially are tough sometimes. There are many many things to try if the Coti is giving you a tough time of it. Some finish better with a very light slurry left on the stone, some with none at all and only straight water. With some you may need to do finish honing under running water from the faucet. Some even like a little oil or for their surface to be burnished/polished a bit (those it's better to stay away from slurry with). So you see it can take anyone a while to dial in a particular stone sometimes.
