With the exception of the 320 grit Chemical stone, which I purchased locally in store, these were bought from Chef Knives to Go. If you are interested, I would point you to that web page for ordering.
All 4 stones had a layer across the top of the sharpening surfaces. I demonstrated this in the video, and was able to remove it with the provided cleaning stone. If this layer is not removed, the knife 'slips' across the stone, with very little abrasion.
The 320 Chemical stone is incredibly soft. For use on large bevels, I think it will perform nicely. However, if using it on a standard 'V' edge, it is easily gouged, and leaves indents in the surface. The stone can develop a very thick mud, if you do not constantly flush it with water. This mud can really help remove deeper scratches from coarser grit abrasives. There is plenty of feedback, and it cuts at a rate, exactly as you would expect, of this grit.
The Suehiro Cerax 700 on the other hand, was fairly hard. Much harder in comparison to the 320. It did gouge, but took some pressure to make it do so. It too, was a muddy stone, if you allowed it to be. The feel, feedback, and hardness were a perfect combination for my own personal preferences. This is my favorite of the 4. Edge performance was nice and crisp, and did not feel toothy like I expected. I will need to use it some more to really get some opinions on performance. It did have signs of dishing after the entire sharpening process was concluded, which is a bit disappointing. Time will tell if it was just from my heavy use in this session, or if that is normal.
Combo stones are nice for testing multiple grits, without having to commit to a full purchase. Though I am not a big fan of them, I appreciate the fact they are available. This one offers 2 grits that are perfect for maintaining sharpness. I must admit I was not happy that the 6k leaves a hazy, muddy, finish. I prefer my higher grit stones, to polish to a bright finish. It is understandable for Japanese knives, that have layers of cladding, and need contrast, to make them visible. In that regard, these stones will perform admirably. Unfortunately, I do not own, nor use, these types of knives. So this combo stone, is not quite what I am looking for. I can now use them for such tasks, should the need ever come along. Both stones (1k,6k) were on the softer side, though nothing like the 320. I guess they would fall into a medium hardness range, if there is such a thing. Like the others, they develop a thick mud, if you allow them to. The 6k had a very creamy feel to it. I think the mud cushioning between the knife and the stone, caused this sensation. Either way, it was a nice experience. Once done, the finish was able to be stropped to a bright luster, though it was not what I would call, a mirror polish. It produced a standard 6k edge, which for almost any knife, is quite respectable. I will have to use this one some more as well, to form further opinions. I did not notice any wear along either stone, and they seem to have held their shape well.

Nice looking stones! I have the little Suehiro 1k/3k (not Cerax) and I like it a lot.
How thick are each stone on the combo?
from chef knives to go:
They are both 185mm long and 65mm wide, but the 1k is a bit thicker at 16mm than the 13mm 6k
@@Jef thanks
Thanks for the review, i thought cerax were splash n go stones.
I can't account for all of them, just the 700 and combo I show here. These certainly require a soak. Splashing water on them just absorbs immediately.
i will keep that in mind. Thank for the info.
The Debado line are the splash and go stones from Suehiro. All the Cerax stones are soakers as far as I know.
Hello! Can i ask, is the suehiro CR-4800 is a soaking stone, or a splash and go? If it is a soaking one, how long it needs to be soaked? Thanks for your answer :)
The 1k side needs to be soaked approx 20 min. The 6k you could probably get away with just min. The 6k side doesnt absorb much water at all
@@Jef Thank you very much! I got this stone today, tried it out, feels good to sharpen on :)
I love my suehiro skg 1000/3000 grit. I wonder how it differs from the cerax. The skg is softer than I nornally like, but the feel is so good. They look alike. But I've heard the cerax is a bit harder.
I think i did a video on that one. Used it twice and gave it away. Was way too soft for my tastes
@@Jef Yeah, it is super soft.
@@dfailsthemost Does it make a scratchy noise, when sharpening?
@@learner5090 No, not that I remember. The 1000 side has a definitely feel of abrasive to it, but not crispy. The 3000 side feels like glass
@@dfailsthemost wow, thanks!
Is Chemical 320 the same stone as Cerax 320?
No. They are very different
@@Jef Ok, thank you.
@@Jef Sorry, I forgot to ask. Do you know What is the difference then?
Everything really. Different binder material different abrasives used. I believe cerax uses ceramic and vitrified. Couldnt begin to tell how the chemical is bound. The abrasive is most likely alumox although im not 100% sure. The cerax is hard. The chem is soft. The cerax ive heard can be used as splash n go altho the versions i have do require a quick soak. The chemical absolutely needs a soak.
@@Jef Thank you very much, that really helps.
What do you mean by “Chemical/Cerax”? Putting those two words together with a / seems to indicate you are saying Cerax means Chemical. I think “Chemical” is an improper translation. That “synthetic” would be a better translation.
That was the name on the box. Google it and search images, you’ll see it. The 320 stone is the “chemical” and the rest are “cerax”. I put a slash to differentiate there are two different sets.

@@Jef Okay, I have not seen that. I still think the Japanese are using not the best terminology translation. I mean what does "Chemical" mean to you? There are really only three main types of Synthetic Stones: Ceramic, Resinoid, and Magnesia. Jon Broida of JKI has gone over Synthetic Stones in his videos. 😎
If you watch the video cliff does on the stone he speaks of one side being formulated to have a tight binder, while the other is more friable. Composition is different on each. Perhaps that is what they mean by chemical? Hell i dunno. It isnt that big a deal to me. A rose by any other name…
@@Jef Right but there are those that think that it might be something totally different than a Synthetic Stone. I still think it is a Japanese translator using Chemical over Synthetic. That the word Chemical as an adjective: "of, involved with, relating to, or made by using chemicals or chemistry". and Synthetic as an adjective: "(of a substance) made by chemical synthesis, especially to imitate a natural product"
im waiting for my cerax1k/3k combo to arrive, any experience on it?
Unfortunately, no. These are the only Suehiro stones I have used. I'd imagine it's like the 1/6k combo. Fairly soft, muddy, with a hazy, high contrast finish. Do let us know what you think, once they arrive. I am sure others would benefit from the knowledge. :)
Hi Jef
have you tried the Suehiro Debado LD 601 .not much review about them ( at least not from people who are not supported by the company"s )
I haven't tried them, but my buddy has. Check out Seth Wright
