This is an extra fine Nakayama Kiita layer, approx. grit size is #10000-12000, Lv.4.5 ,our supplier highly recommend it as a razor's finisher. Very high density, water absorption is slow, Nagura is needed. Regain the sharpness of the blade and its sharpness lasts longer. The sharpening face is not well flattened, if you prefer us to flatten the sharpening face, pls. let us know via message when the timing of the order. Apart from the sharpening face, sealed lightly.
| Please note that these are not for beginner sharpeners since they're harder to use.These are natural stones meaning that every single one of them are different so my measured size are not accurate. This is a life time investment for people who lives sharpening their knives, razors and tools, do not hesitate to ask me your questions|
