I'm no expert on sharpening stones, but wouldn't resting the not-in-use stones like that eventually cause an indent where the edge of the wood is and make the surface uneven?
I would have picked these up for sharpening my wood turning chisels. Glad I checked the specs on the grits. Since they're all crazy aggressive, I'm going to pass.
CJaegerThe grit's they're using for Arkansas soft stone is very inaccurate. There is no way the AlOx stone is more 'fine' than the Arkansas stone.
On it's own Arkansas soft stone is more than capable of bringing a completely dull edge back to a shaving sharp edge with a slight mirror polish fairly quickly (depending on the metallurgy, higher alloy steels and harder steels (60+HRC) slow this process down). I would most certainly recommend an Arkansas soft and hard (finer grit) stone for chisels. Arkansas stone also sells a 'surgical black' (or just 'black' - both are the same, just some sites prefer one name over the other) stone as well, which is even more fine.
according to The manufactures web site info here:
https://rhpreyda.com/explore/
this ex[plains their stones, at least as of today. Does not necessarily mean these are the same stones.
Well, I'd like to buy this product but if the grits are as listed on the posting this would dullen my knives rather than sharpen. Would be okay if the actual grit ratings could be found somewhere else with a certainty of their correctness. But I guess I'll skip this one then, shame really.
Why is there still no word from MD or the manufacturer about the grit on these stones? Massdrop first sold this years ago and people have been pointing out over and over that the grits listed in the product description don't make any sense.
TriNGiven the grits listed for the synthetic stones, no, this is not useful for kitchen knives.
The finest stone (according to Massdrop) in this set is a 320 grit Aluminum Oxide stone. I use a similar stone (from Norton) to set the initial bevel on freshly-made knives, that have never been sharpened before, because it's ridiculously aggressive.
In reality, the Soft Arkansas stone in this drop is going to be significantly finer than that Aluminum Oxide stone. Despite being listed at 220-280, those stones are usually equivalent to about a 600-800 grit synthetic stone. See here for more info: https://www.danswhetstone.com/information/stone-grades-101/
I wouldn't use a Soft Arkansas stone on a kitchen knife unless it was unreasonably dull.
Either this set is badly mislabeled, or... useless. Since I haven't bought it, I'm withholding judgement on which.
If the below numbers are the true specs, this thing couldn't sharpen a crayon. Someone please help me understand this product, as it seems vastly underpowered so I am assuming I have some basic misunderstanding.
Coarse Aluminum Oxide (synthetic stone): 120 grit
Aggressive Soft Natural Arkansas Stone: 220 to 280 grit
Dear Massdrop,
Please verify and post the "Gritt," of the three stones.
I agree with "Dermott," the advertised "Gritt" is way to aggressive.
Thank you.
