I have found Aotos that is usable for razors and knives !!
Grit lv is approx. 2-5k make them super nice Naturals for prepolishers.
I have searched very long time to get these quality Aotos as you know i was very skeptical how slow and inconsistent they are.
It was impossible for me to find very good Aotos and smooth to be used for razor, knives or tools.
But these ones is different they are super nice to use on razors very consistent without any lines or hard inclusions.
Hardnes and grit lv is higher then reguler Aotos !!
picture is just some samples
