We currently have a significant backlog in our sharpening service (3+weeks for everything except initial sharpening)

  • This is a harder aoto, that finishes on the higher grit side of what one might expect for aoto (in the 4-6k range, in my experience).  It has a firm but grippy feel, and was not thirsty at all.  The finish was smooth and even, but, because the stone is harder, there was a bit of streaking around the curves.  However, I found that with a bit of patience and pressure control, it was possible to get rid of them, and have a very nice and even finish.  The contrast between jigane and hagane was pretty nice too.  I was looking for a harder aoto when I stumbled across this one.  I almost kept it for myself.


    Natural stones from this region are rich in silica, which acts as a main abrasive. The potential finish can improve with extended sharpening, with results depending on the stone hardness, the pressure you use during sharpening, water, etc.


    This stone should be used like a splash and go stone... add just enough water to lubricate the surface, but not too much.  The goal is to develop mud, so keeping the surface very wet is prohibitive to mud development.
