Something Friable.

[Blank Blades.]

Does anyone know of any low grit stones that are very friable?

What I'm looking for is something with just a hair less friability than the cerax 320. That stone seems to melt if you look at it wrong. But if there was something just barely less friable that. It would be perfect for what i need.

Maybe the 220 green brick? I haven't tried it so i really don't know about that. Id like to see what people have tried that could fit this description.

Niche! Too many fresh atoma plates taking up space eh?

Shapton Pro 220 is what you want. Fairly soft, fairly fast, good stone imo.

(Though I've not tried the Cerax to compare).

Definitely not friable enough for what I'm looking for. The cerax 320 by comparison is almost unbelievably soft. I just want something kinda close to that, but not quite to that level.

I have the shapton pro 220, its still fairly hard imo. The king 220 is a bit more in the direction I want, but still not quite as friable as i want.

Also, ideally it would be in the 120 range, but ill take what i can get.

This is my Shapton Lapping Disc which I have been using to ease spines. I don’t know if it is the same stuff as an SP120, you know more about that than I do…

But yeah. The kind of thing im looking for is something that will cut hard to abrade steels.

If the stone isn't very friable. It won't slurry like you want, and keep cutting efficiently. So the shaptons, which do amazingly on knives with soft cladding. Won't cut as well on a monosteel blade, thats made of hard to abrade steel. And require the surface to keep being dressed.

The cerax will still slurry enough, but its honestly still even softer than needed. Also, its not really as coarse as i want.

Huh, interesting.

My SP220 is very soft indeed. It slurries and dishes almost like King Deluxes (which is basically most of the reason I like it).

How is that working out for you? I tried the nagura that comes with Debado MD-20 but it's too friable and ends up dishing quickly.

Sigma 240?

Have you considered the Sigma Power Select II 240? Cliff Stamp compared it to the older Suehiro 320 and showed that it was much faster at grinding a CPM-10V blade.

I’m not familiar with Naniwa but I got the 220 version of this thing recently and it melts away quite quickly (way too fast for my intended purpose actually). Presumably there’s a matching full-size version y’all are familiar with?

The other obvious choice would be: any cheap, no-name, combi stone from Amazon, AliExpress, Asian supermarket, &c.

The really cheap ones tend to be very soft indeed.

I want to say the full sized version is the 220 green brick most likely.

Sigma 240?

Maybe. I had just heard in jeff jewells video they weren't as friable as some say, so i didn't pull the trigger.

Though he might have been talking about one of the higher grit ones.

The only thing about it, is finding one thats soft. Some are super soft, and some are ultra hard and don't really do much at all, so its like a dice roll finding which is which.

I did have an asian supermaket stone that was pretty perfect for it. But i wore through it. Though i was hoping someone had tried something more reputable.

Looks like so far the 240 sigma power select 2, and 220 green brick are the options.

Something lower grit would be even better though.

Has anyone tried the coarse lobster carbon stone?

Sigma 240 is definitely friable. Cuts fast and continually though. I'd definitely say it's better for harder mono and higher carbide steels. Coarse diamond stones, not plates, is another option though.

My venev 240 isnt coarse enough. The coarsest venevs might work, or that nanohone one i see sometimes. Its an option I've definitely considered. Havent jumped on it yet though.

 

[Blank Blades.]

Hmmmm. I might see some potential here.

 

[milangravier]

Namikawa 120 grit normal is pretty friable and fast stone. I think you could like it. I can make you a video using it if you want.

 

[Blank Blades.]

Sounds good

 

[enchappo]

Sounds like Milan may have already found the perfect suggestion here, but fwiw my Suehiro Debado 180 is soft and fast. It sounds like there is some variation though, so I might have a particularly soft one.

Or go oil stone and add a sprinkle of loose silicon carbide every now and again to freshen the surface and keep it cutting- I’ve had coarse nortons that work really well on hard monosteels
