Thread: Suehiro Stones

I do love the SG 20K, although I have the feeling for a long time that the stone doesn't take on or absorb any water at all, it's so hard and dense perhaps it doesn't, anyone have any thoughts on this?

you could try to relap it to make surface fresh, not so glassy and clean from human skin oils and etc.
2nd tip - try to add a coupe of drops of cleanser and with a little doze of water cover all surface of the stone.
You will see does it work or not: if it works there will be a darker spot due to water absorbation.

I think you are reading my question incorrectly, there's nothing wrong with the 20K it works perfectly well I use it to hone hundreds of razors each year, and the stone gets lapped on a regular basis, I'm just wondering does the stone absorb any water as it doesn't appear to.

ok)
GMN series can absorb a bit water but it's just about very very thin surface layer. less than 0.3mm. ..I didn't measure it, sorry.
But it's about fresh and clean surface - - after a couple sessions of sharpening water won't absorb almost at all.

I've never noticed any water absorption but then I've never soaked it, just spray and go

I can tell you this, I have had one of their 3K stones for 10+ years and will say its a good stone. It is a very soft stone, I imagine it is to imitate clay based naturals. Its thirsty and must stay wet or it will start to clog. I use this stone a lot with knife making, less on razors. Which series is it...I have no clue. I just know its a 8x3 cream colored Suehiro on a cedar or similar wood base.

For someones HAD:

Suehiro G-8 8000 GC
is quite nice stone , especially for knives with rouge carbide structure (didn' luck with VG-10 knives).
need to be soaked, soft stone..
like nani superstone in hardness or softer, but not so loose as cerax 1000\3000 - it's a lightweight stone with dense surface.
[rus] Suehiro G-8 GC (-- pics of a cutting edge)

I use Cerax 8080 for razors instead because.. yup.. to greedy.
Bit softer, bit loose, need to be soaked. WA insted GC
I don't like nani - too dense and too plastic tactile feelings.

From GMN i like the most GMN-150 because it's easiest to use among all three of GMN stones:
sometimes they work rouger and make ugly scratches --that happens because their density and hardness.
Make surface clean from greese and smooth, less pressure, higher accuracy - hellps to solve.
But looks like i don't need it(GMN-150) for knives or chisels. For razors - I have naturals.
8000 jis is enought for me. +\- nat. finish, of course

=======
Debado series
https://www.suehiro-toishi.com/en/un...bado-3-series/
too greedy to buy it -_-
It's a new series that started ..this year as i remember.
Splash'n'Go.
Ryou, Taiga, etc - no info. All i have: it's not a GMN stones.

New Kouseki
https://www.suehiro-toishi.com/en/kouseki/srk-10000/
omg.. just saw a moment ago.


So.. deluxe, chemical, kitchen series - it's about rouge or cheap stones.
Looks like - that's all.

That's interesting - now don't get me wrong, I have no idea what I'm talking about because, well, I don't have one, but here goes.

Back when I got my Nani's, I used to soak my stones before honing. They worked great. Then one day my combo stone, my 3/8K started to separate and warp. I was told to stop soaking by the vendor, so I did.

Worst advise ever. My Nani's do not cut worth a darn when they are just sprayed down vs. soaked. I had bad hone after bad hone just spraying. The difference in performance for me, when I soak my Nani's vs. spray them is freaking HUGE. I only figured that out after mistakenly soaking a stone again when I got distracted. I'll never not soak a stone again. But that's me... I am NO honester! I'm just a guy with some stuff that makes other stuff sharp if I do my part lol.

That said, the set that I got here, the "Oil/Water" stones, as dense as they reportedly are will be submerged for long periods of time before use. Unless I switch to a vegetable oil. We'll see. All I'm trying to say is I'm a saturation whore. I like em wet!
