Any opinions on the Naniwa Chosera/Pro 600 wrt/ the other stones in that line?
I am looking for opinions of what, if anything, might differentiate the Cho/Pro 600 from its brethren; besides nominal grit level. For instance, I've seen it written once or twice that the 600 along with the 2000 & 5000 are softer than the others, relatively speaking.
Maybe it's just luck of the draw of what internet searches have returned to me, and which blurbs have stuck with me, but my impression is the Chosera 600 is one of the least discussed stones in that line-up.
