...and you can also buy Boron Carbide powder on ebay...Same as they used to make abrasive wheels.. I bought an ounce of it and it's almost as good as diamond but not available in all the grit sizes. Mine is a little too coarse.
Boron Nitride maybe?
To the OP:
Good advice along the way here. If you want to stick with combo stones, get the 220/1000 and 4000/8000. In your original choices, the 3000 and 4000 grits are essentially redundant. You can get by perfectly with a 1000/4000 and a strop with the 0.5 micron green compound (or diamond paste as previously noted). I had a couple of combo stones when I first started and the problem I experienced with them is you get uneven wear on the stones. Your 1000 grit side will wear quicker than your 4000 side and then you're left needing a replacement 1000 grit stone. Combos are an inexpensive way to start, but realize you're really getting half a stone of each grit. I'm in the camp of a dedicated single-grit stone of each grit you need. I reserve my strop for maintaining an edge. I don't use a strop to achieve my initial edge. I stop at 8000 grit.

Its a matter of personal preference.
I don't think 4000 is enough. I go to 8K and I also have a 12K for certain applications.
The 4000/8000 combination Norton is a good stone for the money.
Touching up, I usually jump from a 1250 diamond to the 8K water stone.
You also need lower grits (300, 600, 800 e.g.) too to fix damage or when you've gone too far.

1000- 4000 combination
3000-6000 combination.
I will be sharpening chisels and hand plane blades , do I need both combination?
Thank you for all the information.
I will be doing touch up on the chisel and plane blades.
I have a Jet Wet grinder so I do most of the sharpening on that.
But when I need touch up it is more work to set up the wet grinder for couple of minute of work
I have decided to go with following set up just for touch up.
1 Water Stone 3000-6000 combination
1 Leather Strop
1 Simple Honing jig
Hope this will work
