Thank guys. The main thing is it is super fine and yields lovely smooth edges.
Oh and just realized the wet pic showing the iromono got cut off.

Sure looks my Narutaki. Came from Alex G. Pretty colors indeed. It's my go-to stone for my premium kitchen knives. Still working on figuring it out for razors. Alex said it worked for him, but it's eluding me as a razor finisher right now.
