Grit lv is approx. 2-5k make them super nice Naturals for pre-polishers.
Natural Blue Aoto. Clean and quite hard stone. Very nice Aoto for the price
Good Aotos is very hard to find, also for me so out of 10 i only pick like 3 Aotos that i want to put on my website :(
As with all Japanese Natural stones, Aoto scratches is more shallower then Synthetics stones, make them much easier to remove on finishing stones !
Also they work great as finishers on some Kitchen knives and hunting
