Some are even more, I have one that is more than 5

I met different measurements; out of 3, out of 5, out of 10. But frankly speaking with jnat like with woman. You'll never know until you try. Only with jnat you never regret trying.

yes I am talking in the system Maksim uses.

I don't trust all these systems. Mainly due to two reasons; western people pay too much attention to hardness of jnats, to HGAL, forgetting that there are other very important qualities of stone; second reason - jnat characteristics are changeable, you can easily increase or decrease grit power of jnat. Approximately 3 months back I made experiment with one jnat which originally was Nakayama Nashiji, hardness 4-. Within 3 weeks I used the stone every day with growing progression of nagura stones. Japanese top grit nagura is around 20K grit. I used as nagura one local stone uvarovit, which is extremely hard, it can cut class. In hardness this stone is not much less than diamond but approx. like granate jem. Lapping of such stone costed me a diamond plate, it was completely worked out, but the stone became usable.
My experiment was very simple. One week I used growing progressions of Japanese nagura stones. After that I shifted to my local hard stone. I don't want to take your time with all descriptions. Want to tell the result. After two weeks of usage of very hard nagura modest Nakayama Nashiji became a monster finisher, cutting and polishing at the same time.
After this experiment I do not pay special attention to hardness of jnat. I know I can make from it whatever I want.

I find it useful when I ask for stones that are not for razor to say what I want in terms of hardness so the vendor can find it for me.
On another hand while some pay attention to hardness which as an actual attribute to a stone, others pay too much attention to grits which is not attribute to a natural stone as far as I know.

I don't buy stones for kitchen knives, I have three. Among them two vintage arkansas, which are much better than modern stones. Last time I buy jnats from time to time. I have enough stones for honing, just buy because they are beautiful and I like them. Surprisingly, beautiful jnat is always good, have you ever met this way of measuring jnats?

looks like thread hijacking..
