Herman, the latter edge is after Japanese SJ.
The SJ definitely gives better result than going from a finely graded standard SG straight to the honing wheel.
I understand what you mean, and yes it is possible, but for the Japanese stone to hone out all SG scratches, I should have spent twice the time.
And the Japanese stone is most expensive, and soft and has to be declogged and trued frequently, wearing off quicker than any other stone.
So I limit knife processing on the SJ to acceptable minimum.
All my experience tells me that jump from finely graded standard SG stone to the 4000 grit SJ is way too much.
I have a dedicated SG stone which I grade only finely, and yet I wouldn't rate it at 1000 grit as the Handbook reads - I'd rate it at 600-800 grit.
And when you move the blade from that to the 4000 grit SJ, it's hard to level out all that bad scratches with this superfine stone.
Yet the Japanese stone definitely delivers more than the honing wheel, and for high end knives I cannot skip it.
I wish Tormek offered a dedicated waterstone of true 1000-1200 grit; using it after 220 grit, and then going from it to the 4000 SJ would be just perfect.
