Thread: NOS Thuringians on ebay

So these would rate lower on the grit scale than a yellow couticle?

Anyone use this stone with a slurry?

These are coarser than the vintage Thuringians, similar to the coticule I have. The surface is a bit coarser than that of the coticule but results are similar, some razors seem to do better on these than on a coticule.

If you look at the slurry of these under the electron microscope it looks identical to the slurry of a vintage Thuringian. However the vintage Thuringian has a smoother surface.

Thanks!...

I am slowly sorting things out. I have two Japanese natural waterstones and I believe that I was using them in the reverse order that I should have.

The "soft" stone puts a nice polish on the "hard" one. I wish that there was a way to tell if they are both a higher grit rating than my yellow couticle...the progression seems fine so far when I asume that they are.

I am finally getting some nice consistent shaving edges.

You should be able to tell which stone is finer by how polished the blade is, look at it under magnification, anything is better than nothing. And yes, I believe as a general rule for japanese stones, harder is finer.

Recieved the stone today...nice size.

I appears to have a coarser composition than the yellow couticle. Gritty almost.

We shall see. I will give it a go this weekend.

Have you lapped it yet? The toolshop Thuringian I got was quite flat, but the surface felt really coarse before lapping, much smoother afterwards.

No; I have not yet lapped it...

Do you use a slurry with this stone?
