Thread: naniwa 3k - the hidden gem of my progression

Given that the grit size is halved when the grit number doubles, I've always considered the 2k to be a better option for following the 1k.

When I first bought the Naniwa SuperStones, in order to buy a complete set, I had to get them from two different vendors. Unfortunately, neither of them carried the SuperStone 2k, so I had to buy that Japanese hone from a third vendor in Germany!

I also make use of a 2k following this same logic.
