I've no objection to doing 1/1, I just wanted to know if it mattered, and if so, why.
It's a completely different process.
Typically edge leading strokes are done with
the razor blade laid flat on the hone,
making contact at the edge and on the spine.
At the end of the stroke, the razor is rolled on the spine
so that the edge faces the other way to make the return stroke.
The blade doesn't break contact with the hone between strokes.
I've never seen anyone do anything like that with a knife.
