Very much depends what you wish to do, and then it would depend on your other stones and how much you know how to use them.

I once read than not having a 1K (or equivalent, I use an 800 King) is like having one testicle; if you are setting bevels.

Of course it can be done on a 4K or a BBW and many other hones, but why make life difficult?

Sometimes I go lower than 800 if there are small chips.
