ETA: For convenience, adding details about the stone to the OP.
  • Dimensions: this posting at BladeHQ indicates 5L x 1.125W x 0.25H.
  • Grits: Unknown, including in Spyderco catalog. However, the CBN SM rods as Sal indicates here are "400 mesh." It's fair to speculate this stone uses that same 400 mesh CBN, and the same "fine" ceramic as used in the white SM rods.

For a while, I was interested in this stone. And it's good to see it on the market, more options are always good. But using it as a field stone, not that interested now given the CBN on one side (which is good) and the fine ceramic on the other (which is not, when you want a second practical working grit to use for field sharpening--I can't see a ceramic in this role).

IMO the best options in a dual grit field sharpener are:

* Baryonyx Arctic Fox pocket or field stone
* DMT 2-sided folding sharpeners in grits of choice (I have C/F, but if buying today I'd probably get XC/C)

It'll work for touchups, I'd figure, but probably not wonderful for keeping anything other than a toothy edge on a knife or for maintaining a polished one, in which case the CBN side isn't going to be used.
 
Agree with you both. Adam, I have no plans to get this either. 42, I don't think this is a BAD stone or entirely useless. In general I'm a huge Spyderco fan and like almost everything that company does. However, this stone's RANGE of useful sharpening tasks for outdoor/field usage to me seems limited quite a bit by using the ceramic. The CBN I'd be fine with. Too bad they don't have the CBN (which is alleged to be around 400 mesh) and something more coarse, which IMO, is a more useful combination of grits in the field for both repairing and edge, and getting a quick, useful, toothy edge restored for ordinary cutting tasks. For a typical Spyderco EDC folder though (which is clearly the user this stone is aimed at--and makes sense for that user), where it is carried but only lightly used and rarely damaged, and all the user needs is light touch-ups in most cases: this could be just fine for that. I predict a lot of Spydie "EDC" carriers will get this and love it.

Still IMO, not having tried this particular stone but just going off the specs and known performance of these 2 Spydie materials and grits and having tried the ceramic options myself on Sharpmaker: the AF, or the DMT C/F, either one can do everything this stone can do, can do it a LOT faster, and can do a wider range of sharpening tasks in the field. And in the case of the AF, it is less than half the cost of the Spydie stone as well, so for folks who are thrifty, there is that small detail. :-) For me cost wasn't the primary consideration--I just wanted the most versatile field stone I could find, and completely ignoring the cost, I still went with the AF.
 
It's rather odd that they don't state the grit of the CBN side. And I think they would have been better off pairing the supposedly coarse side with their brown ceramic. It seems as though they're using a bonded CBN rather than coated, and they state that the CBN side is made in China.

I had the same thought; and they also don't state the specific size of this hone, for that matter. Seems like pairing with the brown ceramic might be a better combo, for that one. I'd be curious to try Spyderco's CBN in a format like this; but the fine ceramic on the backside, for me, would likely see little use. Most anytime I use a ceramic anymore (which isn't that often to begin with), I almost always go to the brown. And usually that's been Fallkniven's DC4 hone, lately.

If the CBN on this hone is the same as what Spyderco has used on their Sharpmaker rods, it may be somewhere around ~400-grit, which is how I see the SM's CBN rods described most often.

Sal confirms in this thread what I speculated above: the CBN on the SM rods is 400 mesh. Also this posting at KC indicates the CBN rod grit size is "40 microns" which is consistent with Sal's comment. I'm going to assume they'd use the same grit on the DS2, and combine it with the same "fine" grit ceramic that's used in the white SM rods as well, for similar sharpening capabilities.

Totally agree, pairing CBN with the grit in their gray stones would be useful. I also think the radiused edges are a nice, thoughtful aspect of the design.

Finally, this posting at BladeHQ indicates the dimensions of the stone: 5L x 1.125W x 0.25H.
 
I agree the brown ceramic would have probably been better than a fine white for this stone.

I have never used Spyderco's CBN products. Can anyone that has used them give a comparison to sharpening with coarse grit diamond sharpeners?
 
If so, then the CBN should provide finer action than on the Sharpmaker rods since it appears to be bonded rather than coated. As a result there should be less grit protrusion, producing a slower cutting action but a finer finish.

I don't believe anyone has experience with Spyderco's bonded CBN, though, so I wouldn't take the performance of the coated abrasives as an indicator of what the bonded abrasives are like.

Right, nobody has done testing on the new stone that I can find. But similar to Lapedog's question, it's relevant to look at the comparative performance between the Spydie CBN and diamonds, as Stamp's threads do, just to see how these different media perform in the same sharpening setup. Sadly, I'll never get around to testing the new stone because the ceramic side kinda spoils the pudding.
 
Can't wait to hear about the new bonded cbn. Should resolve the problem with cbn breaking off from people not using light enough pressure like on the rods.

Anyone ordered it yet?
 
The brown ceramic was always the problem. It loads wayy to fast to get any useful sharpening done.
The CBN is an upgrade over the brown ceramic.
However I was expecting a Vitrified, Resin or sintered Bond CBN stone rather then a metal bonded CBN stone.
I don't see any benfits to a metal bonded CBN stone over a Diamond Stone for hand Sharpening.
Price is still pretty high too.
You can get a Worksharp for cheaper that has more options but that thing is huge.

Looks like they still are using the floppy, weak leather too.

Sigh, I'll probably still get one.

There aren't many options that are EDC compact that can bang out an edge quick.

Pretty sure it's bonded CBN, not coated.

That what I thought at first from the pre-order pic.

It was shown as a tan color which I thought was a good indicator of being an actual stone with a ceramic/resin/sintered bond with full thickness abrasive versus a metal bonded plate.

Heres the Gritomatic CBN stone that I thought the double stuff 2 was going to be similar too hence why I was originally excited.

However, one it was released, I saw the real pic from BladeHQ

Dang it. That's just a metal plate with CBN bonded to it just like the CBN rods!
I guess why wouldn't it be. Haha just take the CBN rods and convert them to a metal plate.

I'm a little disappointed since I was originally stoked to get an actual CBN stone. But it's not like there would be any insane performance gains. It would just be interesting to have in my pocket.
Also better feedback and longevity to the abrasive.

Bonded would give better feedback, but would also lower the grit protrusion, which is a feature I prefer by a lot over coateds.
