Spyderco Double Stuff Sharpening Stone, Medium & Fine Grit

This is my first traditional ceramic sharpener and I have to say I'm impressed. I own numerous other sharpening media including DMT diamonds, glass-based ceramics (expensive water stones affixed to a glass base), Arkansas stones, oil stones, as well as Japanese water stones, but none compare to the portability of this stone and its ease of use. Oh, and did I mention it rarely needs cleaning and never needs flattening? I was a little concerned about the width of the stone as I'd always brought the tool to be sharpened to the stone and at 1" wide I figured I'd have to skew whatever required sharpening so that it wouldn't hang over the edge of the stone. Simple fix: Bring the stone to the tool, which ended up simplifying the sharpening process considerably especially for penknives and kitchen knives. The medium grit feels abrasive to the touch and does a nice job of restoring the bevel on a dull blade, while the fine grit is as smooth as a baby's backside and produces a stunning hone. However, if you have a severely damaged tool and need to reset the primary bevel I'd suggest something more abrasive than the medium grit unless you have a lot of patience and a great deal of free time. A nice bonus is the leather pouch, which is not the smooth leather as shown in the photograph but the rougher variety; exactly the type that takes honing/buffing compound and allows you to strop a 'wicked sharp' edge on whatever you're sharpening (keep the stone in the pouch, apply the compound, then strop to your heart's content.) Overall a superior quality tool that's an all-in-one sharpener that even provides a means for stropping if you don't mind one of the surfaces of the pouch getting a little beaten up and soiled with honing compound. Oh, and did I mention it rarely needs cleaning and never needs flattening?

I really like this. I use a Spyderco Sharpmaker for most routine sharpening, sometimes DMT diamond bench stones for reprofiling a blade. But I sometimes just want to sit down and leisurely sharpen a knife while watching TV or listening to music and the Sharpmaker and bench stones aren't really geared to this type of sharpening. Enter the Double Stuff. It's a Spyderco medium ceramic stone and a fine ceramic stone glued together and stored in a suede leather pouch (I've read that the pouches vary, some being soft suede while some are standard leather). Being 5" in length, it's long enough to hold in your hand while using. I've sharpened up to 4" blades easily. Probably not the best choice for your 16" machete, but it's fine for a large folding knife. It works great as long as you know how to free hand sharpen. Cleaning is a breeze, just like the Spyderco Sharpmaker ceramic rods. Any abrasive cleaner like Comet or Bar Keeper's Friend will work. It helps to use a Scotchbright pad. Sprinkle it on the pad, scrub lightly, rinse off and towel dry. You can also just wipe off the metal residue with a dry tissue or cloth while sharpening to extend time between cleanings. The stone is small enough to carry in a large pocket or pack for touch ups while in the field. It doesn't take the place of a sharpening system or bench stones but it's a convenient and handy addition for anyone who can free hand sharpen.

This is an awesome sharpening stone. Light enough to carry in my camping/hiking backpack, along with a mini strop, but so good I use it for quick sharpening our kitchen knifes at home too if I don’t feel like taking out the Ken Onion Work Sharp and only one of two knifes need a touch up. The pouch is made of leather, and can be used as a mini strop if needed (and it works too), although I ended up buying a separate, larger mini strop for easier, more convenient field use, as I tend to strop several times in between sharpenings. I don’t use water with the stone, I use it dry, and it always puts hair shaving edges on my camping, kitchen and EDC blades (I have used it on High carbon steel camping knifes and axes, and blades with 440C, VG-10, Sandvik 154CM and CTS XHP stainless steels, as well as a few Swiss Army Knifes). For harder steels I prefer diamond stones, as they are faster than ceramic and arkansas stone, but this stone could work out in a pinch, it’d just take longer. This is a great stone, and I’d buy it again.

The stone is ~1" wide ~5" long and ~1/4" thick (25 mm x 6 mm x 126 mm). It is white on the fine side and dark brown on the "rough" side. The edges are beveled all around. The two pieces of stones are likely glued together. The soft case is a brown suede leather with the Spyderco logo on one side. The stone fits well in the case. I got it as a 1st step to hone chip carving knifes, I find the suede leather case works as a strop, the last step is new paper polishing. My knifes glides through wood (basswood and mahogany). I also used the stone to sharpen my flat chisels for cleaning up oak cuts. I see two advantages of this stone: 1) it is used dried therefore no mess (ie no oil, no water). Debris do build up on the stone over time, cleaning up involves a quick rinse with something like Ajax, water, and a scrubber. 2) It does not need to be flattened. I have heard that ceramic stones never wear down (ie cup), though logically it must wear down with use, so the wear is probably unnoticeable. The thickness makes the stone feel delicate, I worry about breaking it when it is held in my hand and pressure is applied while sharpening, so I usually lay the stone on a flat surface so the entire underside is supported (use the case to increase grip). I think it should be thicker, or something should be glued between the stones to increase the heft. This is the only reason I give it 4 stars. This stone is easy to use and works well. I may switch over to ceramic stones completely.

This is a very versatile sharpener for even pocket carry. If you want to be able to touch up your blades even when you are mobile, this is just the thing. No water or oil required! From time to time use scouring powder to clean metal from the pores and it's new again. Unlike the old school whet rocks I used to carry there is no dishing of the surface with wear. Well, nothing lasts forever but this comes close. It will break if dropped on concrete or the like. It is not a coarse stone, so don't count on it to reprofile a blade or to sharpen a blade you have allowed to get really dull. Spyderco classes this as medium and fine. Well enough, those are relative terms, but the medium side is probably less aggressive than what you (or I) think of as medium. That said, I carry this for touching up my already sharp knives. There is no need for me to put deep scratch marks that I'll want to polish out afterwards.

This is a handy little sharpener. I use it all the time for both my kitchen knives and my camp knife. Short Version: This gives a very eager edge that will bite very quickly. If that's what you like on your tools this is good. If you want a more refined edge, I would recommend a strop or finishing stone. The medium side will impart a very toothy edge and cuts fairly quickly. This can be used dry, but as with most abrasives lubricant will make it work far better and keep it from loading with steel. Did I mention this will load as quickly as it cuts? Now, the fine side is pretty decent and will refine that toothy edge and still allow it to retain a lot of bite. This side will look like it is loading much faster than the other, that is only due to it being white in color. If you plan on using this as is, I do recommend getting a finishing stone or a strop of some kind, I lapped the fine side of mine with a 1200 grit diamond stone and it is roughly the same as Spyderco's UF grit stone and I think this works much better in combination with the medium stone as it refines a lot of the toothiness and bite and gives a less eager edge.

Spyderco is known for their ceramic stones, and this one has the same stones as the SharpMaker, just in a pocket stone configuration. A few things if you are thinking about this. It's has the medium and fine grits, which tend to be much finer compared to similarly named stones from other manufacturers, so this is a stone for touch-ups and general sharpening, not re-profiling or edge repair. Get the Double Stuff 2 (CBN/fine combination) or the Fallkniven DC4 (diamond/ceramic combination) if you need something more aggressive. As others have mentioned, this is just Spyderco's medium and fine pocket stones glued together (and apparently not the greatest gluing job, although the one I got seems fine), so if you want two separate stones, you can do that, although it's a bit more money. I wanted to carry just one thing, and thought that having a bit thicker stone, albeit two stones glued together, might give it a little more resistance from breaking. Finally, the sheath is the std brown suede. it'd be a bit better if the stitching went up the side another 1/2 inch. But, you can load it up with stropping compound and have a final finishing step if you are into that.

These are the same stones that are used in the Spyderco Sharp Maker sharpening system, which I own. One side is the grey medium grit stone and the other is the white fine grit. These are flat stone that are meant to be held in your hand and used to polish out any nicks on your blade. the size makes it easy to toss this in a pocket or a pack to take care of your cutting edge on the go. this stone is big enough to use as a small bench stone, but it is thin so you will need to place it on the edge of a block to be able to work the knife on the stone, but it is also small enough to use as a file on the edge of a larger blade. this is not for the beginner to knife sharpening because there isn't any angle guides or instructions that come with this. It is just a double sided stone and a leather case, plain and simple. Care instructions are wash the stones in warm water with a mildly abrasive cleaner, and air dry. this only needs to be done when the metal particles have built up on the stone that it isn't removing much of the blade material when being used. they are made from ceramic, so they will chip easily, so keep them in the storage case when they are not in use. Not that it matters, but the leather case that came with my stone was a much darker brown and is more of a suede style leather.

Es una verdadera maravilla. Excelente la calidad de Spyderco, no decepciona. Esta piedra y un asentador de cuero es todo lo que se necesita para reafilar y mantener tus filos en buenas condiciones, después de usar ambos lados, el filo queda para afeitar. Si bien aunque esta piedra remueve acero con relativa facilidad si tus filos están muy dañados o mellados es recomendable usar un Grit mas agresivo(una DMT Coarse o XCoarse, por ejemplo). Tiene el tamaño adecuado para llevarla a todos lados lo que resulta muy practico. Para aceros como el de las hojas de Vitorinox y el 8Cr13MoV saca rápido los filos. Es Excelente recomendada 100%

The usual high quality sharpening stones from Spyderco, except in a pocket sized version. The leather sheath makes a great honing strop as well, cleans up my manix 2 blade in no time. With 5 minutes of work you can take a dull blade to hair whittling sharpness. If you own a Spyderco knife, especially a full flat grind version, and you don't have this sharpener. Then your EDC is incomplete.

Très bonne Pierre pour un affûtage sur une lame non abîmée, seul petit regret, j’aurais bien aimé avoir la pochette en cour blanche 👍🏻

Dieser Zweiseitige Schleifstein ist sehr gut für den Feinschliff geeignet. Um Kerben aus der Klinge zu schleifen oder gar einen neuen Winkel anzuschleifen benötigt man etwas gröberes, wie den Fällkniven DC 04. Getoppt werden kann der Spyderco nur noch durch Abziehleder. Der Schleifstein hat eine angenehme Größe; klein genug für die Hosentasche, aber noch groß genug um ihn wie eine kleine Feile in der Hand zu halten oder auf einen Tisch zu legen und das Messer darauf zu schleifen. Das Material nutzt praktisch nicht ab und nimmt dennoch genug Stahl vom Messer ab. Die Lederhülle ist sehr praktisch und schützt den Stein vor Beschädigung; brechen kann er aber immer noch.
