There's a a first time sharpening session with a knife and then a routine maintenance sharpening session with a knife. Once you've created your bevel with a coarse stone (sub 1k) then it's easy to follow up later on with a 1k stone, however, some 1k stones (IMO - like the King) cut way too slow and dish way too fast which then allows for multi-facets to be cut on the bevel (AKA - bevel rounding) and cause problems. So what I advise is to look for fast cutting stones at the lower levels.
