If you watch a youtube vid on traditional sword sharpening you will see the use of those little chips, I guess they are the finest abrasive available and only sold in very small pieces. Sword sharpeners use them as a final polishing step for the surface of the sword, not so much for sharpening.

Yep, those chips aren't for creating slurries or whatever, they're for the final polishing process. One rubs them against the blade. A Nagura stone on the other hand, works very well as a "cleaner" of waterstones. In fact, it is marketed for both cleaning and creating the slurry, which eases the sharpening process.
I often just clean my waterstones on very fine grit sandpaper. It's cheap and it works. I haven't noticed that the sandpaper would leave any particles on the stones. Since the stones are so soft compared to the sandpaper, I'm guessing that the particles from the sandpaper aren't dislodged and baked into the stones.

That's exactly what I thought too, but the shopmaster said no! I was quite surprised. He wouldn't give me any grit reference for the Nagura and kept calling it a 'finishing stone' but did say that the 12,000 grit water stone was MUCH finer. Go figure...
Maybe it works via another action?

There is an empty apartment on the third floor of the building across the street. if you want to move in, all you have to pay is "Key Money" (about $5,000 US, non-refundable when you leave,) a refundable damage deposit of about $1,500, and first and last month's rent - $3,000. This will get you an apartment with the floor space of a very small one car garage and renting for $1,500 US.

Ouch! Which country do you live in?
Japan. That apartment is what's called a 4½ mat room. You can get an idea of the size here; http://en.wikipedia.org/wiki/Tatami

I'm starting to get very good results but still need the 8k stone to do things right. The scratch pattern of the 12k is a little confusing, the edge when done feels very smooth and very sharp like after using chromium oxide but the edge finish even when the stone is loaded is not as polished as you would think it would be. At 100x is where I saw the real scratch pattern though, to the naked eye it looks similar to 2k sandpaper but under magnification it looks like a edge that has been polished with micro abrasive. I can get it to whittle hair sometimes, something I find strange because of how sharp the edge feels, cuts flesh like no other though 
The other thing I find a little odd is that 1 micron diamond compound is too fine to properly remove the marks left by the 12k.

Yeah I find the 1 micron diamond to be finer and comes after the Naniwa 12k. Well 1 micron is 15-16k so that's what I would expect.
With thread test the Naniwa 12k performs worse than from a 1k stone in cutting the thread, but when I shave with it, the Naniwa 12k is indeed a lot sharper than the 1k. I know it's sharp... just couldn't find a test to prove it other than to shave with it.

Its very "different" you could say, I like the sharpness and cutting ability of a edge after my DMT EEF better but the 12k was not really purchased to improve on sharpness as it was to improve on finish. I can't lie though the 12k edge is about as good as you could ask for without the use of a loaded strop.

Diamond compounds or $10k in waterstones but I'm not rich enough for those stones. I did find a good deal on a natural finishing stone... $750 shipped.
Of all the polishes I've used diamond compounds yield the best polish and sharpest edge, yes it will be a perfect mirror if done correctly.

Go ahead and buy the natural finishing stone. Only $750 sounds like a real bargain....then make me a good deal on the Naniwa 12K that you will no longer have a use for. Just trying to help.

How's $750 sound?
I tested it out on some CPM-D2 that was already polished to best see the results. I was happy with the finish but the method of letting the stone build has raised some questions.
In this pic it looks like metal smearing, opinions?
400x
Looks nice at 100x though

That last photo is about as perfectly a polished edge as I've ever seen. I'd like to use a stone like that just once. I've heard about them, but never seen one. I don't know if I even own a knife whorthy to be run across that stone. Anyway, nice job!!
