I too never understood the Bread-knifing bias.
Years ago I was taught by a master carver to sharpen chisels, hone 90 degrees to the edge to remove a chip and get to solid steel. Then sharpen the bevel, by first honing at 45 degrees, to near meeting, then honing at the proper degree. It only takes a minute to do it that way on a grinding wheel or stone.
The same for a razor, remove the chip, then high angle hone the razor (45 degrees), with the spine off the hone, to where the bevels are almost meeting. Then hone normally, you should be able to set the bevel in a few minutes.
Either way, you will remove exactly the same amount of material.
