I have a big chunk of some kind of nagura that works for me in that area. But it takes ages. In fact, technically speaking any stone can set a bevel for you, just depends on how much time you have available.

However, if you are a man with things to do and people to see, forget a finite-time natural bevel setter and just do what the rest of us do: buy a decent synthetic or diamond, and check the hones section every 6 months or so for any new info on finite-time natural bevel setters.
