That one is HUGE and very clean hard Aoto, also extra fine ! Very hard to get Aoto that big and sooo clean !
Grit lv is approx. 3-7k make them super nice Naturals for pre-polishers or even finisher for many knives.
It is very rare i put Blue Aotos for sale as they tend to come to scratchy and to soft
This one is is very consistent and very smooth clean aoto that is super rare now
Have some small cracks that is normal for such big stone, they can not be field and not toxic so as always i recommend to seal it !
