Then, consider I have done this experiment, since I strop and shave directly from the 8K for this past year, and it goes smooooth...

Oh, Nenad, also, why is .35m the thinnest you can hone a blade?
True, it would get overhoned, I just think overhoning happens not if you spend too much time on the hone, but also if you add some pressure to it.

as for the .35m, beats me... that's the exact measure that SEM measured on the DE blade and professionally honed razor (coincidence? I don't think so.) I think the razor's cutting motion is not ripping parts of the hair shaft, like in hand cutting with the hacksaw, but getting the edge between the layers of hair cells and splitting them apart. Teeth, or stirations have no business there...

Also, the comment from the barber's manual (I have that printed and laying on my work table for 5-6 months now) is likely the author trying to explain cutting on the basic level, not knowing how it actually goes. If you remember the "microscope" pictures (drawings infact) you will see a saw edge, with teeth, which don't exist on the real SEMicroscope images even at 2-3000x magnificationm on both DE blade and straight razor...
