Recommend me an edge finishing/kasumi stone

[EdgeFundManager]

Current stone lineup:
Shapton 120
Shapton 320
Naniwa Professional 1000

I am looking for a higher grit stone that can be used for edge finishing and will provide a decent kasumi polish when refinishing. Preference is for splash and go synthetic, but I am open to other options. I am pretty happy with the edge off the Naniwa 1000, so maybe I just need something that leans toward polishing performance. I considered the Naniwa 3000, but from what I have read it’s not great at polishing. This is new territory for me, so I am asking the experts. What do you suggest?

Calling @cotedupy as a coticule/bbw combo would likely do you wonders.

I second the BBW (Belgian blue Whetstone). Google might direct you elsewhere if you simply use the acronym.

For a slightly more aggressive synthetic option I highly recommend also the jns synth red aoto.

Big b... ok ok Belgian blue whetstone. That BBW is ok, uncle Ed not fan of other BBW.

In my experience, your two stated preferences - 1) splash & go and 2) synthetic are counterproductive to a "kasumi" finish. If you're looking for a lot of contrast and less visible scratch pattern, I'd suggest looking at some natural options. Without going crazy you could definitely hunt down an ikarashi, natsuya, akapin, soft iromono, etc. that will be easy to use, not break the bank, leave a nice contrasty smooth finish. If by kasumi you mean the really nice "scratch-free" iridescent polishes you can see of higher end polishers, your gonna need patience and naturals.

Of stones that do fit your requirement, a Morihei 4k would be my choice (there is one in BST for what its worth)

Hard to really say what others consider "great" but I have used naniwa pro/chosera 3k in the pre-polish phase to remove scratches. It can leave a decent kasumi as well

Aggressive in terms of edge/teeth?

Yes. Maxim lists it as having a mix of 2k-4k grit. To me, that sounds about accurate.

Maxim has quite a few smaller but decently sized Lv 2,5 Aiiwatani's on his site now.
If they're anything like the one I bought years ago they should be a good fit for you.
The gap from a NP1k is large , but doable if you finish very lightly on the 1k with some slurry on the stone.
I suck at polishing, but my Aiiwatani is like a cheat code. Basically flawless cladding with very little effort.

Belgian Blue Whetstone is a shoe-in for this as @esoo said. I don't know anything natural or synthetic that would fit the bill better.

Interested in the BBW. Is there a preferred vendor for quality? Would something like this be good:

I will check out the other suggestions too (thanks everyone!). I find naturals interesting, but I know nothing about them and find all of the names, grading, etc a little overwhelming. I probably need to do some homework.

I got mine from here
https://www.belgischerbrocken.de/lng/en/blue-belgian-whetstone-sharpeningstone-coticule/?count=40
They offer larger sizes. I got one approx 8x3" plus a slurry stone for right around $100. Depending on the current exchange rate, it may be less.
