Natural Stones- Grain Orientation. Does it matter

Wed Jul 18, 2012 7:25 pm

Today I received a Amakusa Natural Stone in the mail from the nice people at Chefknivestogo.

This is the first natural stone I've ever messed with. It feels significantly different than man-made waterstones. I like it, though. The edge seems to "talk to you" more when it's reaching the highest polish it can (on this particular grit,) if that makes sense.

My question is this. Does the orientation of the grain of the stone matter?

I'll use wood terms. Should I be sharpening on the quarter-sawn (end grain) side or the plain/flat-sawn side?

I assume it's intended to be used on the quarter-saw/end grain side. The stone had the edges beveled on this side as if it were to be used this way.

I did and it produced a good result.

For some stones (naturals) the is a difference. For the Amakusa it shouldn't be too critical so try it both ways.

For those natural stones from Tanaka Toishi, that have the stamp matching my avatar on it, the optimal side is the side selected as being finished smooth. This is particularly important for various aoto and suita type stones.
