Disagreements expected - one might counter your opinion with an assumption of your use of aggressine pressure on the Ark to cut the bevel back to a flat surface. No disrespect intended - just sayin' - different strokes, ya know?

At any rate - rounding the bevel on leather, linen, or crox on linen isnt unheard of or undocumented. In fact - Iwasaki references a slight rounding of the bevel after a coulple of passes on what I believe to be Crox in one of his printed manals.
I do strop the heck out of an edge, agreed I dont find this to be the culprit or an absolute either. For example, that C135 I had probably wouldnt round if you dragged it behind a car fir 20 moles, On the other hand, I had an old sheffield of unknown origin would round and/or dull if you yelled it it.
What I can say for sure - is that one persons or one group of person's experiences doesnt make a fact. Having said that - I do know fior a fact that repeated burnishing if steel will put a curve on what was a flat surface, and a curved bevel will eventually lift the edge off the hone in a static state, like when one uses too much pressure on a full hollow.
Hey - someone once wrote that they had a Cnat that was as good a finisher as an Escher. Maybe they do. I tend to believe more than I disbelieve to be honest, so If someone says they get good results with a Trans as a touchup stone - so be it. Me - Id rather touch up on something thats cuts a bit more, I get better results that way. My mileage varies, depending on how I drive.
