Spyderco Double Stuff Sharpening Stone, Medium & Fine Grit | Double-Sided Ceramic Stone, Perfect Carry-Anywhere Sharpeners

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?

Good points: -Gives you a very nice polished shaving sharp edge -Product fit and finish is very nice (they took the time to radius the stones!) -Very nice quality leather sheath doubles as a strop for final polishing in a pinch -Ceramic is of the hardest materials known to man, only second to Diamonds -5 inch length provides a workable length to sharpen knives on without being overly awkward -Good value for the money -Ceramic is VERY long lasting and will pretty much never wear out Things to be aware of: (Note I didn't title this "bad points") -Although Ceramic is very hard, it is also brittle by design and will shatter if dropped -Ceramic by it's very nature is a fine abrasive and is more geared towards the finishing process. So if you have a chipped or damaged blade, don't bother using ceramic. You will be there all day! Instead use a different sharpening medium for heavier stalk removal. -Ceramic loads with steel faster than other abrasive mediums such as diamonds or synthetic stones, so they will require routine cleaning. Simply use some Comet cleanser and a NYLON scrubbing pad with water... Do not use steel wool or you will simply load the stone with more steel. Bottom line: Keeping the above in mind, I think this is a great sharpener from a great company. Give it a try!

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.

The stone itself works great, and it fits just fine in its leather sheath. The only minor problem I have with it is that its difficult to clean the metal shavings from whatever I was sharpening off the stone. Water and a cloth doesn't seem to work, and if you soak the stone too long then the two sides will come apart.* *I didn't do this, but enough other people have that I felt I should mention it.

The Spyderco Double Stuff Ceramic stone has a medium grit on the brown side and a fine grit on the white side. The coarser medium stone is excellent for refining the initial blade, while the fine stone leaves an excellent cutting edge. I personally use a leather strop to add one more way of getting the sharpest bade possible. while no lubricating is required, I personally like to use a drop of water to help keep the metal shaving floating away from the bevel. Simple, easy to use, and if the stones get congested from multiple uses, just use a little ajax and scrub the stone back to "like new" condition. In a pinch, the leather pouch can also be used as a strop. This is a good stone to make beginners good and experts better.

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.

This sharpener from Spyderco is really rather good. I’ve had one for a few years and turned the leather case into a strop with a bit of jewelers rouge. A little bit of dish detergent on the ceramic stone while sharpening helps to clear away the build up. The ceramic is a fairly fine grit even on the medium side. That being said I don’t use this for profiling mostly just touch ups when I’m out camping or even at home for some of the smaller knifes. The first time I bought this the price was around 28 and at that price it’s a good purchase. The last one I got for a friend more recently and it was up to 35 dollars which let’s be honest is kinda a high price for what you’re buying. Over all a good product that does a good job of putting a sharp edge on a knife. Update It’s June 2020 and the glue of my spyderco double stuff has given out, after a year and a half of hard use I’m left with a very thin smooth and medium ceramic. Still good value for money.

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.

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.
