Hi there,
I thought I would post this here as it's a specific question and I'm hoping to reach others who use this stone.
I've been using it for a few months, but I've not been completely happy with the edge I've been getting (on various steels, blue#2, victorinox, CCK).
I mostly use the SP1000 and I'm very comfortable with it. I get a burr, flip, burr, flip again, lighter pressure, burr, flip, lighter pressure, burr, then do some alternating stropping strokes (5,5,4,4,3,3,2,2,1,1,1,1,1,1 or something like that) until the burr is gone (but depending on the steel, I may do some edge leading strokes to remove the burr a bit more aggressively earlier on). This gives me a good, sharp edge. I can push cut newspaper against the grain.
But I move on to the Aoto to refine it a bit. I use lighter pressure, not aiming to make a burr, but just looking at the scratches on the bevel. I finish in the same way (light stropping strokes). The first few times I used it, I kinda felt a more refined edge, but I also noticed it was not as sharp. It would slice newspaper in a more refined way, but it would no longer push cut it (in any direction).
I noticed the stones surface was not flat (which must have happened from factory), so I flattened it, and this helped, but it was still not as sharp as the SP1000. I had another go the other day, and I was about to give up, and when I was putting the stone away I realised the surface was not clean. I had not been using a nagura of any sort (I usually look at the surface to see if it's clean, but because of the colour, I realised you cant see any grit). So I got a nagura and cleaned it up and finished again with stropping strokes. The stone felt completely different, much less resistance as the knife went over it (much faster, like skating on ice), and I got a better edge. Improvement.
But I tried another knife yesterday (blue#2 petty), using the SP1000, and then the Aoto, making sure the Aoto's surface was flat and clean. My final edge was definitely better than before, it cut the paper well, but I still felt it was not as sharp as the SP1000's edge. I'm not expecting the Aoto's edge to be sharper, but just more refined (although I understand it's a mix of grits, but it's still higher grit than the SP1000), but it's the fact that I feel it's getting less sharp that I'm possibly doing something wrong.
Doing just a couple of swipes on a leather strop improves things, so I'm wondering if there's a tiny burr, but if there is, surely there would also be a burr after the SP1000? I also did not have this problem going from the SP1000 to the SP5000, I always felt a big improvement in terms of sharpness and refinement (although I have since sold that stone as I didn't enjoy using it)
Thanks
