Svord has videos of sandpaper use to convert a peasant knife to a convex edge. I start with 800 for a dull knife and take it up to 2000. 2000 gives a nice edge for the kitchen.

Overall I prefer the results of a spyderco triangle sharpmaker to sandpaper/convex method. Touching up a convex edge with sandpaper in the field has obvious benefit in terms of portability, however...
