These are the natural stones I have tested on razors: mostly hard finishers from Nakayama, Ozuku, Aiiwatani, Kizuyama and Oohira. The hardness is written as Lv in each stone name, and for razors most people end up between Lv 4 and Lv 5+.
Every stone has its own description with hardness and best use. If a stone has toxic lines or inclusions I write it there. If nothing is written, there are none.
Picking a razor stone is personal. Email me before you buy, tell me which razors you have and what you sharpen on now, and I will help you find the right one.
