I just sharpened a Henckels paring knife. I think I sharpened it before a long time ago, but it was really dull. Took quite a few passes on the A100 belt (180 grit) before I finally got a full length burr on both sides.
I deburred with a VF scotchbrite (blue) and then bare rough leather. Edge seemed pretty good. Sliced phonebook decently. But I decided to take it to the BESS. I knew half way through I had a problem. Too much force was required. Sure enough, it scored a 500! Jeez...
So I slid my thumbnail down the side of the blade towards the edge, feeling for a burr. Sure enough I found, not a normal tiny burr, but a "step" that my thumbnail bumped over. I'm pretty sure this would have looked like Line Of Weld under a microscope. Back to the VFSB. This time I felt each time with the thumbnail slide. I checked both sides, did some more shallow angle strokes on both sides and... I could no longer detect any "shelf". I considered doing leather, but I could not see any burr or feel it. Let's try the BESS again: 150! Really? Let's try another spot (nearer to the tip): 155. Ok, I'm satisfied with that.
Apparently I need to spend more time with the VFSB and less with the leather. This steel is pretty soft, so I'll keep that in mind in the future. Harder steels will probably behave differently.
I'm very happy to have discovered this combination of tools, measurement, and advice (Hi Grepper!).
