Naniwa Japanese waterstones are hands down one of the best stones for sharpening a Straight Razor, if not the best. They are fast cutters, yet have a butter smooth feedback very similar to a Natural stone. Unlike most other brands these do not need to be soaked before use, just spray some water on the surface and start sharpening. We do not recommend these stones for knives, as they are softer than most stones due to the binder they use. Unless you use a knife angle guide on the spine to prevent the edge from digging into the stone, which is not a concern with a straight razor.
Note from Phil: Some may remember that very short time when we sold Glass Shaptons. I am asked every so often why we do not sell them. The list is too long to write here, but know that cracking stones, wasn’t our biggest issue. Basically they were a gimmick (in my eyes), and one that I honestly cannot understand why they are still on the market. Ceramic has it’s place in the sharpening stone world, but not as a Full baked Ceramic stone. It is great for longevity and cheap, but that is mostly it. Naniwa uses Ceramic in their stones like many others, but it is added to the matrix, and use binders that compliment the sharpening process. It’s a very fine line to get a good quality finished product that works. Luckily for us, we did not sell many and refunded every sale. Now this does not mean they may not be good for axe’s…..
