Actually, for maintaining a razor in good condition, or restoring an edge that is just dull, a norton 4/8 is all you need.
Or you can use just a coticule.
either one will do the job.

having a multiple of stones is nice (I have several myself) but not a requirement. several members here have over a thousand dollars in stones, but that does not mean their razors are sharper than mine.
It just means that they can pick a stone for each razor which they like best for that type of razor.

As for the 220/1000 I really advise you to learn using it on project razors that you don't care about.
Even with the 1000 you can really do a lot of damage in a single stroke if you don't know what you are doing.
