Chuck, I only advocate using the steel stock to break-in stones when there are high spots or clumps of abrasives your looking to knock down or even out. The sharpening experience you gain through continued sharpening use of your stones can’t be replaced. As you continue to use these stones you will learn how to discern through the feel, (i.e., the sharpening feedback), and the look of your scratch patterns on your bevels as the stones improve and become consistent when they’re broken in.
If you’re really anxious to get your stones broken in I’d only use the coarsest grits on the steel up to but not including the 400 grit. The 400 grit on up get used quite a bit more then the coarser grits and break-in fairly easily with 8 or 10 knives.
