I’ve been interested in the Naniwa 純白 (Junpaku/snow white/pure white) 8000 grit sharpening stone since I got my first Naniwa Chosera stones. The Snow White is not a part of the Chosera line, but it’s considered to be the poor man’s Chosera 10,000 grit stone, coming in at less than half the price of the 10k Chosera. It’s even cheaper than the Chosera #5000.
The problem was that the stone wasn’t available in Europe, so I asked knivesandtools.nl (where I bought my Chosera stones) if they would consider importing it. They did, and also sent me a stone for review! Knivesandtools.nl is their Dutch site. They also have an English site.
I’ve tried out the Snow White together with my 1k and 5k Chosera. It feels a lot like a Chosera stone in that it’s hard and fast cutting. I understand why people call it “the missing Chosera”. It’s of course smoother than the coarser stones, but it also feels much harder than the 5k stone.
