Honing a slight S-shaped blade

[commiecat]

So I recently received 8 razors in an auction and decided that the ugly duckling in that lot, a William Bingham razor, would be my project razor.

I've been polishing it up and it's actually looking pretty good. I've also been acquiring a basic honing setup; DMT 600-grit (W6F), 1200-grit (W6E), 8000-grit (D8EE), a Norton 4k/8k and a Swaty 3-line.

I'm gonna use this to practice my honing but the problem is that the edge is slightly shaped like an S:


If I hold the razor perpendicular to a flat surface, the edge will touch at two spots. My question is how to hone this. Should I breadknife first on, say, the DMT 600, or is there another way to tackle it? Thanks for the help -- this is going to be my first strokes on a hone.
