For a new knife with a good edge, you would be chewing up the edge needlessly with this stone. Use a cc4 to start, then if you really work the edge dull, go onto this one to bring back the edge. Finish with the white ceramic of a cc4. Make a strop out of an old belt glued to a piece of wood. Apply a little green polishing compound and you can get an edge to shave with.
good luck. Check YouTube for some helpful vids.
