Just ordered a few of the cerax stones for my single bevel knives. A member here recommended Suehiro stones to me about 2 months back, maybe he will see this thread also. I wanted to say I decided to get some Suehiro stones and try those for the next few years and put my king stones aside.
I've been trying lots of new companies and seeing if any of them have decent stuff to offer. I picked up a TorchTree (I think, weird name) and tried to rough polish a batch of white steel honyaki at 65 HRC. The 1000 grit side of it got demolished by a single blade and didn't even manage to properly flatten shinogi before it got turned into a valley. That Torchtree is garbage if you ever see those stones avoid them, no offense to the company but that's 20 smackers down the drain could almost buy a King Kombi Toishi rough combi stone for £26, and that will at least cut a batch of hard knives without needing to be flattened every 5 seconds.
Anyway enough rambling about that garbage stone, I should take a pic of it and show the valleys in the morning.
Are the Cerax stones any good? they seem like good hard ceramic and have a veriety of grits from low to high.
Had to order them direct from Japan so they won't arrive for another 2-3 weeks, hence why I'm making this thread, I want to know if the hundreds I just laid down is going to impress me and eat through these hard 65 HRC cutlery, going to need to be cutting through 4 batches per month, from 1mm edges down to thinned out. So if these stones can last at least 1 year before they die I'll be impressed.
My kings last about 4-5 months per stone before they are dust.
 
I have the Cerax 320 and 1K.
The 1K is an amazing stone that I wish I had bought years ago.

The 320 is good but not my favorite in that grit range.
What stones did you order?

I have tried about 8 or so Suehiro manufactured stones and they are all well worth what I paid for them.
The Rika 5K is an outstanding stone also.

The downside to the Cerax line is that they are soaking stones but that is not a big deal to me.
You should not have any problem with grinding Japanese white paper steel at a high hardness.

1000 700 320 and naguras. Picked up another King K-80 as well because I love that stone, not sure why exactly it's just handy.
The soaking is no problem I have a few stones permasoaking in lasagne dishes, my kings spend more time under water than on their drying rack haha,
It's good to know that all 8 stones pleased you, that's a good sign. I was lookin at one of those 8000 suehiro polishing stones as well, it's not a cerax but it looks very good quality.

You should get on well with all those stones.
I don’t use my King stones a whole lot anymore but they were the first water stones I ever used when I worked in a cabinet shop in the early 90’s.

I have gone through a few 800 and 1K King stones over the years.
The Suehiro stones are more aggressive than the Kings and a bit more resistant to dishing.

Hopefully they arrive sooner than expected.
 
If you like finer edge's the Suehiro G8 stone is a great 8K stone and one I my all time favorite stones for finishing,you can pick one up off ebay right from Japan cheaper then you can from most dealers.

Thanks for the recommendation, that's how I'm buying my stones nowdays as well, from Japanese online sellers on Ebay, Etsy Amazon etc.

I've used the 1K. It's softer and muddier than Choseras and Shaptons. Good stone, but unless I need the mud I prefer harder stones.

I am looking for harder stones, that's becomming more important to me, I do need slurry though for specific stages of polishing. I was looking at Shawns vitrified diamond stones, but I'm not sure about the 500+ price tag, I could get some very premium Tennen Toishi imported direct from Japanese mines for that price. The vitrified stones do look very impressive though, I can see myself grabbing one eventually.
 
Are you US based? MTC kitchen and sharpening supplies.com both sell them. Amazon does also.

I have the 3000. It’s nice, not as great as everyone on a different forum seems to think. But it’s nice overall.

I'm based in London UK, thanks for the suggestion, I don't always use UK based companies, I will order things from America, Europe or Asia if they offer things I can't get here.
