I’ve tried using sandpaper for sharpening, although not with a dedicated jig like in that article, just a honing guide and a flat surface. Have to say that it works quite well. Tons of info on the net – google “scary sharp”.

But… while it is less messy than water (or oil) stones, it doesn’t produce any better results, provided that you keep your stones flat. And in the long run, stones are way cheaper.
