Have a look in the Advanced Honing Topics section: "Honing a concave/warped blade."
There's a good discussion on using a narrow hone, as well as how to simulate a
narrow hone.
The technique really does work, but I'm not sure that it would be a good place
to start for a beginner. It sure is a lot easier to learn to hone if you start with a
razor that doesn't have any geometry problems.
