Thank you very much EOU and Mr. Grepper for sharing your views on this conplex topic.
For the time beeing I am not deepening the idea of the "foil effect", but rather considering how universally valid the obtained results are, and to what extend they may reflect some specific properties of the A2 steel. This includes grain size, carbide size, carbide hardness vs abrasive grain hardness etc.
Also the question came to my mind if sharpenning/honing could torn out some hard carbides from the matrix and leave a deffect in the edge.
