Thread: What is the name of this hone?

Can any one help me to find out what kind of / name is of this hone?

I is dark brown , makes yellow slurry, hard stone , about 12 K grid.

Thanks

Is it after it was lapped and cleaned? Otherwise the colour could be mixture of old oil and muck.

Yes,

after it was lapped and cleaned. The pic shows some blue into it but it is moltly dark brown and some redish spots.

JSZ

it is thuringian stone.

Hmm,

never knew that thuringian can be brownish but it might be . It cuts well but the finish is not as good as Escher. Came from Eastern Europe as well so.........

Thanks

Hi Bud Gl

Try use with oil without slurry and see what happens . gl
