Gentlemen
Thank you for your passionate and good advices.

I believe learning is a process where progress is made by making
mistakes AND not repeating them. Todays theory of "knife edge" on top
of bevel was debunked. I did manage to shave with it, not a perfect shave but
a shave still.

A 8000 grit stone is ordered and in the mail. I use the generic chinese ones from
aliexpress as, well, i still have no clear idea what i really need an what not. Whenever
i know what i'm doing i'll get decent stones and some beautiful gold etched straight razor
but meanwhile as learning is done, razors overhoned and stones used unevenly because
of perhaps wrong type of honing i'll stick to the cheap ones.

And for a last comment there was no way to guess DE blades have an intentional
double bevel. Thank for that information.
