Thread: New Shapton M5 12000

0.3micron paper won´t fit into normal git ratings. Ie. it is not 18.000 or equal to.

0.3µm is as low as it gets, there is no synthetic stone this fine.
So the only thing you can be sure of is that it will cut finer than most if not any stone you come across.
So technically it is not near 18.000 but much like 60.000 or 100.000...
But that´s just speculation and won´t necessarily mean better shaves.
But you should definitely experiment with it
