I'd agree that the 1K hone is a workhorse bevel setter if you are doing razors with chipped edges or a lot of corrosion on or near the bevel and that is doubly so as the grinds get heavier. That is a lot of heavy lifting to do.
The 3K hone is fine for edges in decent condition that just need a bit of work to reset them.
All I have ever used is a 1-3-8-12K progression or 3-8-12K on the better condition edges and that seem to cover most all eventualities.
