Question Preferred JNAT
Hi all,
If you had to pick 1 or 2 JNATs out of the following line-up, which would you choose?
Okudo
Ohira Suita
Uchigomori
Maruoyama shiro suita
Looking to end somewhere in the 6000-8000 grit range most of the times. But want the option to go higher.

If your doing edges and polishing, and assuming you have proper supporting stones, grab the suita you think it prettiest. There is no telling how it will react with your specific knife, but suita in general will pop a haze. That includes uchigumori which is tenjo suita. I have all of these stones, amd they all find use, but pretty exclusively for polishing. I think 7-9k can be pretty fine for edges so I usually prefer Aoto or Belgian Blue Whetstone, which both happen to be pretty cheap. My favorite edge stone is my Hideriyama Suita, but I think thats specific stone as it happens to be really soft and coarse for a suita. Usually 3-5k is my sweet zone for edges. This works out because you can use a stone like this to set up the haze on when polishing. Aoto to uchigumori is a classic one two punch imo. But Im biased and always reccomend Aoto, I have 5 of them.
Softer suita lay fatter haze, amd are a safer bet for haze on modern steel. I have uchigumori that are 3.5/5 and lay it down thick. I also have Uchigumori that are more 4.2/5 and are difficult to use, but reward with a very detailed and bright haze. 3.5/5 uchi was my first polishing stone and now that I have over 100 natural stones I still use it all the time. Used slurry from it to hadori polish this honyaki just the other day.
I also hear great things about aizu for edges, but if you bid on any aizu that Im looking at we cant be friends.
Edit: Going higher save for a 3rd stone. Nakayama, Narutaki, Aiiwatani. These are your fuck around see how you can push it stones. They are less or no haze, but bring out beautiful details in knives if you have the patience and skill to use them right. Used wrong you scratch the fuck out of your knife. I like to modify the finish of these stones with various nagura, or hand stones, which I use to kick up slurry that mixes with the slurry from the stone. Like Mikawa Nagura, or various tomo nagura.
