I just started shaving with a Dovo 5/8, badger brush and paddle strop a few days ago. I'm getting a reasonably good shave but realized that the razor probably isn't sharp enough out-of-the-box.

I just ordered diamond pastes (1.0 and .5 microns) and a double-sided sharpening strop from classicshaving. My question is this: will this equipment put a good edge on a new razor and will it be enough to maintain it? My idea was that if I used the pastes, the blade shouldn't dull to the point where a stone is necessary. Am I correct or should I get a stone as well?

Thanks in advance!
