I use 3 grades of waterstones for all my tools.
I cheat and use a honing guide for chisels and planes because fettling a blade that has lost it's flat bevel is a pain. The finest stone tends to glaze and i sometimes give it a quick dressing with the second grade to get a paste and remove the glaze. I think you can get a proper thing for the job.
When I'm out I have an arkansas stone for touching up the edges. Soon I'll have a DC4
For finishing fine edges I have a peice of wood covered with leather (think of somethig like a flat file) one side is dressed with flexcut gold the other is not dressed at all. If I'm carving I give my knife a couple of strops on this every now and again to keep it keen.
