"even if the razor rest stable on a hone" Do you mean rests?
" build-in" perhaps built-in . . .
I would really emphasize the importance of equal pressure, stroke angle, distance, direction, etc. on each side of the bevel. I still think a lot of people miss the idea that a centimeter or two farther on one bevel edge creates havoc on geomtry.
You say it, but its hard to over-emphasize these things.
But you know . . . thats just me.
