Thread: Chosera or Naniwa for Bevel Setting?

Thanks for correction!

My sharpening experience is not limited to straight razors only. I sharpen all my kitchen knives, folders, chisels, planes, scissors and so on.
Because of such a broad experience my vision and appraisal of stones differ from traditional of this place.

Yes. Chosera are based on magnesia bond and have higher concentration of abrasive grain than SS.
So they are faster, but there are some downsides of such a bond.
Chosera stones can produce a cracks on the surface when you try to dry them too quickly.

It has already been discussed on another thread: http://straightrazorpalace.com/hones...can-crack.html

The relative humidity in Japan is high and very stable ( 65-75% ) so there is no such problem with stones if you are living there.
But in other regions the humidity is not as high as in Japan. In urban environment with district heating in winter the relative humidity in quarters could drop down to 10% or even less. In such a conditions special handling is needed to prevent the Chosera stones from cracking.
For example one can use humidors.
