You can also find softer stones that work well with a clear water finish to boost the edge a little, on some softer stones it works and others it does not contribute much.

Tom, have you tried adding 20-30 light clear water strokes? I assume that you're finishing on slurry.

Hi Steve,

What I find with the harder iromono is that they don't seem as hard as the glassy hard Asagi grey stones, because the slurry has a softness to it, yet some feel just as dense. I am wondering if this is do to with the grit richness of a lot of the iromono stones along with a high level of finess. So the stones are still really hard sometimes, but they don't give that glassy feed back and feel much more alive.

Yes , I do use clear water stokes on many iromono and on my super hard ones sometimes I need to add some slurry strokes because it is so sharp and a bit harsh on my sensitive skin. I however have not had enough time to try the clear water stokes yet on these Narutaki Nakayama polishing stones. I have on some of the iro Okodu i got with the same shipment and found I like the overall feel finished with very light slurry vs just water so far. That may also depend on the razor too though. Also when I do clear water strokes I use alot of water and zero pressure like the razor floats, so it is like finishing under water. If that makes sense.

Enjoy,
Tom

Odd name. Aren't Narutaki & Nakayama 2 different quarries ?

It depends I guess if the name Narutaki is used to describe the mine Narutaki or the area Narutaki, of which Narutaki and Nakayama are mines in that area

Narutaki is also a type of stone used in the final stage of sword polishing and can come from different mines this particular one came from Nakayama.

Just saw Fikira's post and I would also guess that they name this final finishing stone which comes after Uchigumori for the region it comes from too, but not sure on that. I just recently found out that it can come from various mines.

Seems a generic term as well as a quarry.
