Nice videos I just wonder why there are so many scratches on the bevel when you use a 4 stone setup ... shouldn't the surface be without those if you erasede the scratches from the previously used stone before you went on to the next = end up scratchless when you hit the final polisher?
As a customer - bought a couple of stones - I actually expected an answer to my question. Seems like it's getting ignored so I will try again.
You write that one actually just need 3 stones - well 4 including your JNS 1000 - but it says that 3 is enough! When buying J-nats I would expect that a very nice finish could be expected - when I manage to get the skills. Since I'm not a hardcore sharpener - but would like to be - I look and study many pictures of stones and the way they can polish knifes. I have seen great examples ... a great one is shigefusa - their polish is out of this world
So when studying your pictures I looked at each one and compared the results. The JNS 1000 produce scratches - fair enough. Then the aoto is used - this create some haze. The suita makes the surface polished again which makes some of the previous scratches visible. You end up with the Maruka as the finishing stone. On this picture I actually see even more scratches ... and this is the final polish.
As mentioned in the post above I believe that one has to erase the scratches made by the previous stone before moving on to the next. This would be the case thruout the entire setup. As a beginner in this field I only can imagine what the right procedure is, but for me this 3 stone setup seems like too little - or mis-matched. Wouldn't it be better to use like a 5-6 stone setup and then be sure that all scratches would be erased properly = a perfect polish? If it would, which stones would you recommend in such setup?
Photos can lie sometimes. If you look at 1600x1200 pictures:
You can see that focus between the two are different. Fo Ohira's finish picture, the focus is more on the body, while for Nakayma's finish picture, the focus is a little deeper into the bevel.
But don't forget that some harder stones can scratch soft jigane. (Though I'm not implying that in this case)
Impatience is your enemy.
How can you make a statement that your novice, and straight after that you think it is impossible?
How hard could you try in the time you are actually training polishing?
You talk to a guy who polished plenty of knives and have huge knowledge, if he said three stones are sufficient, then that is so.
How do you know youre technique is right, if you have no experience? Especially the pressure applied.
Its just about the same as with knives and chefs - some thinks you have to have expensive setup of blades to work well, even though we all know its BULL SHITE.
As to the scratches, there will be some visible simply cause the background is more evenly finished.
If youre not happy after three stones, try fingerstones, one knie is around 5 hours, if your further unhappy, use cork with mud gathered.
Ater try polishing with felt pad.
I managed with three stones, I can guarantee its possible, take your time to practice!
you do realize those are 3 independent stone mini demos?As mentioned in the post above I believe that one has to erase the scratches made by the previous stone before moving on to the next. This would be the case thruout the entire setup. As a beginner in this field I only can imagine what the right procedure is, but for me this 3 stone setup seems like too little - or mis-matched.

No where did the OP say they have to be used as a set.
I am very sorry for my late reply Peco !
Those videos is max 1.5 min polishing and just a demo of a finish they make.
There is no such thing scratch free surface, to make scratches less visible you need to get them all in even direction, like Shigefusa dose.
If you twist Shigefusa knife in the light then you will see that scratches is much bigger then you expecting
So if you use more then 1.5 min on etch stone you will get better result
And as other said in that thread the harder stone bring up those scratches from previous stones and make them more visible, so you need to use more time on Harder Jnats
Those videos was just to get idea how stones work, speed and finish. I did not try to get perfect finish for that demo
