What is the best Nagura for synthetic stones?

I'm looking to make more mud on some of my stones. Gesshin, Chosera, King, etc.

I used to use a diaface 600.

I have heard good things about the 1500 as well.

But recently i have started to just build up mud the old fashioned way, sharpening. Then lightening up once the desired mud has been generated.

The thing is some just don't make mud like my Chosera 3k - feels gummy on some steels and gets black, but doesn't give up the slurry. I permasoak it too like my Gesshin 400 and Beston 500. My Mino 1k is fine as is my Gesshin 400.

Magnesia based stones, like the chocera, should not be permasoaked. Permasoaking will lead to cracking.

I read soaking was fine and haven't experienced any cracking on it. It's been in water for six months and no problem.

It's your stone, Mike. Do be aware that the first signs are crazing on the surface.

I stand corrected - it's a Naniwa Super Stone

naninwa will never develop mud, at least nowhere near what a king does. I've found those stones perform best if you keep them wet and keep too much swarf from buidling up on them as well. They made me wish i had a sink bridge

Good to know I wondered why this stone collects swarf so fast. I'm constantly cleaning it as I sharpen. 3k does leave a nice, slightly toothy edge for proteins.

I use this all the time on harder less muddy stones. It works well:
