IME it is one thing to breadknife a few chips, or even a large chip, out of an edge and it is another thing to breadknife a frown. I've done it on two razors and it took forever to get a bevel back. Will the blade lay flat on the hone ? Do the marker and if it will lay flat see if an x stroke with the blade at a 90 degree angle to the hone removes the marker for the length of the blade.

If it will do circles (more like ovals) alternating with back and forth strokes until you get a good TNT from heel to point. Once you get that go to x strokes and clean it up further until it will shave a bit of arm hair. Proceed from there, you know the drill. I don't know if that way is right, wrong or indifferent but that is what I would do.
