Thread: Yet another J-nat to identify

Hello guys!

Could anybody help me to identify this stone.

All I know about it is that it is from Japan.
It is very hard and have rather good abrasion.

This is a tomae strata stone, what I usually call a iro (color) tomae. These iro tomae are often very nice stones to use, they slurry up with a diamond plate to create a butter smooth paste that you have to add a touch of water to often. Stones of this color came from the shallower tomae strata and get their colors from several sources: oxidation, and water soluable alternate minerals. Also these semi soft stones have not been so affected by any heat or pressure like the deep strats stones have. It should be a splendid stone to use, looks like a hand held hone size and shape.

Some Tuesday morning "truth." Quite refreshing, thank you Alx.

Thank you very much!

As far as I know the japanese for this iro tomae is 色物 or 戸前 色物

And now I have found the stone looking like my.
Here it is 菖蒲谷・色物 :
Natural whetstone Shoubudani Tomae


And here it is one more: http://www4.ocn.ne.jp/~kanetake/syoubu.html



The only difference is the hardness. My is substantially harder.

As for slurry my iromono performs very well with slurry removing steel much faster.

Beautiful stone!

Sharpen something on it and show us what it can do.

Yes, iro means color, mono means things.
