Thread: Maruoyama stones, how do they perform?

Anybody have stones from Maruoyama? Would be interesting
to learn about heir hardness, finess etc.. how they perform.
They have all type of stones from different stratas.The owner of the mine
has a website : “V‘R“uÂ�ÃŽÂ�ÌŒ@Â�Eâ€�ÃŒâ€�„Â�@“uŽæ†°Ã†Â�i‚Æ‚Æ‚è‚âÂ�jÂ�y‹ž“sÂ�E‹T†°ÂªÂ�z.

Their stones are usually for knife and plane blade sharpening. but
they now sell stones specifically for kamisori. This is the Kanji:
大谷山 戸前浅黄 カミソリ砥(Ooyaniyama Tomae Asagi Kamisorido)

Mainly softer stones good for knives/tools, also I do not think you can buy outside of Japan, language barrier I was told.

Stefan, they do sometimes answer to English emails. They
definitely sell outside of Japan, I asked. I think
it was the cousin of the owner who speaks english a bit.

Using translation software the description of their kamisori
stones say ''carbide mouth'' which I guess means super hard
stone. It also says needs nagura.

Great try one and let us know how they work out.
What I heard was they are softer stones because the mine is newer and the stones are from the softer upper strata.

Anybody have experience with Maruoyama stones?

Thanks for replying Maxim.

Do they cut all steels? I have a few naturals that don't cut
softer steels, but do cut HSS steel! I can't understand why
because the HSS is very tough steel. Only thing I can think
of is that because the HSS is so tough it actually releases
slurry from the hard natural stones.

Oh yeah I think they are now in the Aisa strata.
