    Golden Review Award: 4 From Our UsersDas Ding ist einfach super. Als Koch habe ich mich jahrelang mit den blichen Scharfmachern wie Wetzstahl, Schleifsteine in verschiedenen Krnungen, Vidia schleifer, usw. abgemht und bekam nur schlechte Ergebnisse.
    Wenn ich dann eimal die Messer ,und ich habe einige gute, zum schleifen brachte, sind sie zwar scharf, aber verhunzt und runtergeschliffen.
    “Geht nicht anders?”
    Doch geht.
    DMT Macht es richtig, schnell mit wenig Abtrag, aber dafr gleichmig .
    Ich habe so viel Spa damit das ich jetzt schon in der Nachbarschaft die Messer Schrfe .

    Have been using this mostly to keep a draw knife sharp during heavy use. Has been working very well. Was worried about the base a bit but no movement or rocking with a very heavy hand-forged tool. I appreciate the handle on the bottom, I use it to work on the bevel side.

    I reshaped the bevels, sharpened, and stropped 2 hatchets to a shaving sharp edge in less than 30 minutes. Kitchen knives only required a few strokes on the fine side.

    Golden Review Award: 8 From Our UsersJust remember it needs to be broken in before you can expect the grits to be accurate. Also, the coarse side is not as coarse as you would expect, if you want to remove a lot of material (to form a primary bevel for instance), get something coarser or use something else. Definitely designed for pre-finishing.

    I bought this with a course/medium stone. You have to be a bit careful with the coarse stones, they’ll chew metal away faster than you think.

    That said, it’s a very fast, and with steady hands and a bit of practice easy, way to fix or set an edge. I used it on one of my older kitchen knives; much faster for fixing an edge than my water stones, though I still used the water stones once the edge was set to get an almost mirror-smooth edge.

    I would probably get a 6″ one, knowing what I do now. The 8″ works fine, but can be a bit unweildy and the extra space isn’t really useful for even my 7″ chef’s knife.

    Golden Review Award: 54 From Our UsersVorab eine kleine bersicht der Krnungen dieser DMT Platten:
    Es handelt sich um ca. Angaben, manche Krnungen gibt es so nicht genormt aber die Zahl zeigt wo sie ungefhr liegen.
    grob=45Mikron/ 325Mesh/ P320/ F235/ J360
    fein=25Mikron /600Mesh/ P600/ F340/ J650
    extra fein=9Mikron/ 1200Mesh/ P2500/ F700/ J2000

    Ich habe jetzt schon einiges an Schrfzubehr (Tormek, Bandschleifer, Lansky, verschiedene Steine etc.) ausprobiert und muss sagen dieser DMT begeistert mich enorm.
    Primr habe ich ihn in Fein/Extra Fein gekauft um meine Zwilling Cermax Kochmessersammlung mit ca. 66 HRC (z.B. Zwilling Twin Cermax Kochmesser, 200 mm (Pulverstahl, Micarta, genietet) schwarz mal eben schnell in der Kche nach zu schrfen und das funktioniert wie geschmiert.
    Hrt sich allerdings nicht so an!!! 🙂
    Das einzig negative was ich beim DMT gefunden habe, ist das kratzende Schleifgerusch welches er verursacht.

    Aber nun zum schleifen:
    Messer stumpf (schneidet nicht mal mehr den Kchenschwamm)
    -> DMT auspacken, Schluck Wasser drauf, das Teil steht dank der Gummife die anfangs etwas chinesisch riechen bombenfest
    -> 5x drber ziehen pro Messerseite Krnung Fein = 10 Zge
    -> DMT Platte mit 2 Handgriffen umdrehen
    -> 5x drber ziehen pro Messerseite Krnung Extra Fein = 10 Zge
    -> 5x pro Seite Abziehen auf dem Lederriemen mit Polierpaste = 10 Zge
    Messer rasiert innerhalb von 5 Minuten.

    Der DMT erhlt meine absolute Empfehlung. Schnell, einfach, sicher.
    Mikroausbrche lassen sich mhelos rausschleifen.
    Fr grobe Kerben sollte dann aber schon was anderes her. z.B. der DMT in Grob oder halt schnell und einfach der Bandschleifer 🙂
    Dank der enormen Gre von 152 x 67 mm auch fr groe Kchenmesser geeignet.

    I bought this after seeing a demonstration sharpening down at Woodcraft. I sometimes regret not getting the longer one but this sharpener works great for my chisels and such. According to Jerry at Woodcraft, the diamonds stay sharp forever. I also use it to polish my plane soles and to touch up my Starret square faces. The fine side really polishes metal well. A quality tool.

    Just fantastic! I have about a dozen knives to keep sharp in the restaurant, all different sizes, weights, and grades of steel. With this I can get to them all once or twice a week to keep them in good shape. Not quite razor sharp but certainly a good edge for what we need. With a little extra time I’ve managed to bring a couple of the knives to a very keen edge. What I like best about this is how easy it is to use. Splash a little water on in, sit down with a knife and in 3 to 5 minutes I’ve got a good edge again. I bought an angle guide to use with it but after some practice I’ve found it’s not that hard to keep a consistent angle freehand, so never use the guide ( which didn’t really work that well with the longer knives )

    Golden Review Award: 2 From Our UsersGreat sharpener. It is super simple to use and is incredibly flat. Just a little bit of water and the occasional wipe down to remove the leavings and you can sharpen forever. I used it with the Robert Larson 800-1800 Honing Guide to completely rework 4 old chisels and my block plane. The combination resulted in better than new tools.

    The only warning I’d give is that the “coarse” side is slow at removing a large amount of material. So reworking an entire face (like I had to do with the chisels and plane iron) will take some time and elbow grease. But it’s a good workout.

    Works as described and it’s easy to catch the hang of. Restore your blades to surgical sharpness. I have all of them now starting with coarser one and graduating to extra fine. Made in the USA and I recommend it.

    I’ve used cheaper diamond stones and they just don’t work as well.

    Golden Review Award: 8 From Our UsersIn short: I had to use a diamond stone to flatten my water stones, so why not use diamond stones for the entirety of my honing process? After a lot of reading on what grit of DMT stone I needed to mirror my old waterstone process, I finally settled on this as the centerpiece of my workflow. And I couldn’t be happier. The results I get equal my previous waterstone set-up, and I spend a lot less time and hassle getting there.

    I highly recommend buying this set-up, in addition to a DMT course stone. With those 3 grits, and a honing strop, you’ll easily equal a 10k+ waterstone produced edge and spend a lot less time re-setting bevels, or removing large imperfections.

    What a great tool! I use this on my plane irons, chisels, and kitchen knives and have nothing but love for it. Unless your blades are damaged (big chips or nicks) or you want to reset the angle of a bevel on your plane iron, this is probably the only sharpening tool you’ll need. I have a set of Norton waterstones that I’ve been using for a little over a year but they have worn down very quickly and get out of square easily even with diligent use of a flattening stone. I needed something else for my woodworking tools.

    The DMT DuoSharp is very, very quick–no mess, easy to use. I used to take my blades over to the Norton waterstone 8000 grit to put a final finish on them after using the DuoSharp, but honestly, now I just strop my blades after using the Green “very fine” side of the DMT stone. Your blades come out razor sharp in two minutes or less if you know what you’re doing.

    Get this for sharpening, you won’t be sorry!

    Golden Review Award: 2 From Our UsersSuper nice stone. I have a box full that I use for kitchen, hunting and butchering knives. Decided I would spend the money for a high(er) end stone and base. I love it. You can feel and hear the difference with the first swipe. The stand is plastic with quick release clips to flip the stone. Does not move at all while using on a standard countertop. If the clips actually last several years, it will be an even better value. No oil is a plus, especially for a quick touch up during butchering… just swipe, wipe and continue cutting. The coarse/fine ratting isn’t really standard compared to most others. I would say medium/fine would be more accurate. An extra coarse/extra fine stone would be a perfect mate. Probably can see that in the future. Wouldn’t hesitate to spend the money again.

    These are well-crafted and durable products from DMT. My only complaint is about the item’s packaging – why is an item sold as new arriving with the manufacturer’s packaging torn open, leaving me to wonder was it a return, and resold, and if so, why? I notice a trend of this, and I am just enough of a stickler that I expect an item purchased and paid for as new to be that – including the packaging being intact. Otherwise I’d buy on eBay…

    For woodworking chisels and panes, unless in terrible shape, I use the DuoSharp, first a few passes on the fine side and then more on the 1200 mesh side. I finish off with a Shapton 5000 stone. I use to take my tools in to be sharpen but now am using this method. This method appears to work well. I restored by grandfathers plane, 1903, that I found in an old tool box. After rust removal, I flaten the sole with a progressive sandpaper, sharpen the blade to 5000 and also worked the cap iron a bit on the DMT fine side. It is my best plane. My kitchen knives are now very sharp after a few swipes on the DMT. My advice is once a sharping session is over, to dry the DMT before storing.

    A good sharpener for your knives that have a decent (but dull) blade. The holder and “stone” are good quality, holding the “stone” firmly and being stiff. It’s taking a little “getting used to” to sharpen my knives with this diamond stone (vs the traditional honing stone), but after a few less than successful attempts I finally have the hang of it and can (and have) put a decent edge on all the kitchen straight knives and my pocket knives.

    Don’t try to use this with a serrated blade, it won’t work, otherwise, it’s goof for most normal blade lengths.

    You may want to consider a sharpening guide if you’re getting this, like me, without much experience. The guide will help you avoid scratching the finished surface of the blade (if that’s important to you) and will help put the right angle on the cutting edge so you don’t round the current one or blunt the edge.

    Golden Review Award: 4 From Our UsersAfter using water stones and sandpaper to sharpen my woodworking tools for the past few years, I began to get frustrated, in particular after trying to regrind a moving fillister iron, and decided to go another route. The DMT has been held in high regard so I decided to give it a try and it has not been a disappointment. I’ve reground several older plane irons in just minutes using the DMT. Had I used water stones alone, that process would have taken far longer. A quick honing can be achieved in just seconds. I still use an 8000g water stone for final honing, and a leather strop for carving tools, but all of the main work is now done with the DMT Duosharp. Another important feature is the fact that the system requires no maintenance and can even be used dry, though I use water, or window cleaner. Since I purchased the Duosharp my tools have never been sharper, and more importantly, have never been this easy to sharpen.

    Brilliant. I thought I was just a talentless clod for not being able to put a decent edge on my tools or kitchen knives. I read so many articles that make sharpening sound like a dark art, but like everything else the quality of your tools matter. This is a very good quality tool and I’ve been able to put excellent edges on planer knives, kitchen knives, putty knives and block plane irons.

    This is one of those tools that make you “happy” all the time. It’s always a pleasure to use a cutting tool that has an excellent sharp edge on it, whether it’s cutting veggies in the kitchen or planing an edge.

    I took a totally dull 7 inch cheap kitchen slicer knife and with a combination of the extra coarse, coarse, fine, and ultra fine diamond stones turned that knife into a scalpel. I was able to slice a ripe tomato with total ease no thicker then the blade itself, almost as thin as three sheets of paper. These stones are amazing, took about 10 passes on each grade of stone on each side of the knife. About 7 minutes total. Impressive.

  51. Erica says:

    Sharpens so fast compared to the old stone I had there is just no comparison. And the fact it is 8-inches wide and two-sided only adds to the 5 star review. It stays put, easy to flip to the other side and uses water as a lubricant. I couldn’t be more satisfied and have sharpened my knives to almost (and maybe actual) razor sharpness. Yes, you can cut paper with the knife after.

    One minor drawback – no edge guide included, although they are available on Amazon.

    With the various knives and single and double bevels, it isn’t hard to get a very sharp edge on any knife. I can slice a hoagie bun with a chef’s knife and hardly leave a crumb after using the sharpener and a steel for final edge straightening.

    Not for use on serrated blades.

  52. Geoffrey Morrison says:

    I’m not sure on the price for this level of equipment, but it works very well. The base is rigid and holds the diamond stone well. Flipping the stone on the base is quick and simple. I wish I would have found something more fine at times, but this is great for general knife sharpening with kitchen, hunting, and daily blades. i feel like a natural stone for finishing would be needed to hold an edge longer anyway, so having a finer diamond stone probably wouldn’t be too productive.

    Great sharpener. Finally I have a sharpener I can keep handy in the kitchen for the kitchen knives.
    Just add water. No oily mess like my old stone. It doesn’t sharpen as fine as my old stone, but it’s close. And it’s much less of a hassle and mess.
    Sharpening my knives on the old stone was an ordeal, so it didn’t get done as frequently as required
    This diamond sharpener his easy clean up so it’s actually a joy to sharpen up the blades.

    This sharpened really puts a fine edge on the knives. Note, if used frequently, clean it with a 3M pad or similar as it removes the metal quickly and will load up. Not a bad thing, just the by-product of doing a good job.

    Golden Review Award: 2 From Our UsersBack in the olden days of high school Industrial Arts, Mr. Zander would give you an “A” for the day if you could sharpen a plane iron razor sharp so he could shave arm hair with it. This product would have made doing that a snap. I’ve had experience with using diamond abrasives and main thing to remember is don’t try to force work with a lot of pressure and don’t be afraid to use too much water. The abrasive is tearing off chunks of steel (swarf) that if allowed to remain between work piece and backing plate, will cause the work piece to actually ride on top of swarf and prevent contact with abrasive. I’m retired, I bought this to use in my home shop and I like it.

    This is a great stone. I use mine along with a Veritas guide to sharpen plane irons and chisels. As with any sharpening, keeping a constant angle is essential. One advantage with these diamond composite stones is they don’t need flattening. I dip it in water every few minutes. you can’t go wrong with this double sided stone.

    Got this for my father in law for Christmas and he loves it. I have an old DMT sharpener that belonged to my Dad who passed away in 1999 and I still use it and it is the best. But you can bet that I am asking my wife for one of these sharpeners next year.

    Golden Review Award: 2 From Our UsersVery high quality sharpening bench. With a little practice this can tool can produce a very sharp edge quick and easy. After using this bench stone I finish up my knives on a strop and they are hair popping sharp, no problem.

    Well I bought this guy and the Dmt d8ee 8inch dia sharp continuos diamond (extra extra sharp) for the finish result, however I’m just talking about this one in this review. First of I purchase this stone with the purpose to sharpen my chefs knife. it is an awesome product it will sharpen your knife super quick, may take a try or 2 to get use to it but is well worth the purchase, don’t be afraid of purchasing diamonds, only advice is to no apply pressure let the diamond do the work. The result of both stones is a razor shaving sharp edge! good luck!

    This sharpener did what it advertised. You need to know how to hold your knife before it works. But once you learn that, it only takes a few strokes. Am pleased with it and will take to our daughter’s place this weekend to sharpen her knives with it.

    Golden Review Award: 3 From Our UsersI have a Spyderco Sharpmaker that keeps all my pocket knives in tune. I’ve got a few other cheaper stones too. For some reason I’ve just been delaying buying a decent diamond stone. Maybe I was being cheap and just didn’t want to spend the money. The DMT DuoSharp is worth every penny. After hitting all my folders and fixed blade woods knives, I let loose on the kitchen cutlery. This left me wondering why I didn’t buy one of these years ago. It made the wife happy too.

    Golden Review Award: 3 From Our UsersThe stone itself is hard to fault. It’s fast and will put a nice fine edge on your steel. Kitchen knives should still be honed, and other knives stropped, for the best edge.

    My only note is that the base can provide, essentially, too much stability for some purposes. Allowing the stone to rock back and forth ensures that the surface is in contact with the blade. With the base, you’ll often find yourself using only the edge of the stone as the blade isn’t perfectly parallel. A simple solution is to put something like a couple towels below the stone such that it can move with the blade.

    This is a great sharpening stone combo. Nice and big with a sturdy base that stays put. It’s solid too, so water doesn’t get trapped inside when rinsing, unlike another combo stone I have. Nice to have the flat unperforated area at the end for small tools.

    It made all my knives and cleavers sharp….easy to use too. I keep this in my kitchen drawer, so I can use anytime I need.
    I hate dull knives and I cooked a lot. So far, before I found this I was using ceramic knives…still using them but now the other knives useful too

    Golden Review Award: 2 From Our UsersThe stone works well, and true to it’s nature, very quickly. The base is light, but holds the stone well and really is a nice addition. There’s actually a handle on the underside of the base… for certain tools, I actually prefer to hold the base in one hand and the tool in the other (sort of like a sharpening steel) – at least for me, the handle is very useful.

    I ended up buying this, along with an extra-course, course, and extra-extra fine stone (and the DMT Wave, too :)). I’ve sharpened about 7 lathe chisels and a kitchen knife and am very happy with the results. With the kitchen knife, I took it all the way from extra course to extra extra fine, and finished by honing on a leather belt… and it really came out with a very nice, sharp edge. Very happy with the stones, can’t wait for them to get “broken in” after prolonged use.

    Golden Review Award: 6 From Our UsersWhen I order this product, I liked it because the picture and description said that it comes with base(as you can see the base is black and hold the bench stone). However, when I received it instead of the black base, this product comes with a silicone flat blue piece. The black base (as it shows the product) is sold separately. Surprise!!!! It cost $15 more.

    This sharpener was everything I expected it to be and more. I have been able to quickly sharpen all my planer blades using the DMT and a rolling angle guide. There are many videos on YouTube showing how to do this. If the planer blade is only a little dull, it only takes 5 strokes to restore the edge.

    Golden Review Award: 2 From Our UsersI bought this based on the comment from the user who said it was great for their Global kitchen knives. I bought it for the same reason. It puts a fantastic, functional edge (e.g. slice a piece of paper without tearing) on the blade in just a few swipes. I have not managed to take anything to a razor-sharp (e.g. shave hairs off your arm) edge. I think I need a finer grit for that. However, I do know what I’ll be getting my dad and FIL for Father’s Day.

    Golden Review Award: 2 From Our UsersGot one of these for my kitchen knives and serious knives. I have used natural stones and love them, but they are labor-intensive. I tried this one and am hooked. My kitchen knives were my test knives, and it took less than a dozen strokes to put an edge on my chef’s knife that would literally slice a free-hanging length of toilet paper with ease every time. I found that I can easily and quickly put an edge on any knife I own that is just ridiculously sharp. I think I will be using DMT for the rest of my life.

    Exceptional product. I own a number of very expensive knifes that need periodic sharpening. If you own any Asian cutlery you know that the recommended sharpening is on a stone. Well, this product is much steadier and easier to master and doesnt require advanced honing skills. Love it.

This stone is far better than the blue or white stones. Puts an edge on faster. It seemed expensive at first, but after using it for a coup,e years, I can’t go back.

    Bought this and the Coarse/Extra-Coarse stone at the same time. Sharpened all the knives in my house in one evening and now everything stays nice and sharp all the time. Scissors? No problem! And the base holds the stone securely up off the table. A great investment!

    I thought this would be the best product to sharpen plane irons and thus far it has performed to my expectations. I thought it would get them fairly sharp, but it doesn’t get them razor sharp. I will have to buy a high grit waterstone to achieve the level of sharpness I’m looking for. I would recommend this for all types of sharpening. The plastic holder has a handle on the back side so it is versatile.

    Received the product promptly and I’ve got to say, I’m impressed. I’ve used a decent number of tools and techniques for sharpening knives over the last couple of years (oil-stones, water-stones, alum. oxide, multi-thousand grit automotive sanding papers, etc…) and this is one of the faster and more efficient products I’ve used. It took me all of ten minutes to go through a number of knives that I had started sharpening up and put a fairly good edge on them. I think I could do with some finer stones for polishing, but so far I don’t see a need beyond professional pride.

    Golden Review Award: 2 From Our UsersThis is the best sharpening system that I own– others include the Smith’s PP1 Pocket Pal Multifunction Sharpener and Smith’s DFPK Diamond Precision Knife Sharpening Kit . While those have features that I also appreciate (such as size/portability and the knife guides for precision sharpening), this is definitely the system to choose if you’re sharpening the knives at home (as opposed to out in the field).

    This stone is LARGE– enough to accommodate even my biggest kitchen knives in one pass of the blade. A few (maybe 10-15 on each side, alternating 5 at a time) passes are sufficient to restore a paper (or tomato) cutting edge on my knives. This does make it more bulky for actually taking camping (I’d probably stick with one of the smaller and more portable options), but for the right tool at the right time, this can’t be beat.

    Because I like to sharpen my knives regularly, I find myself using the extra-fine side the most– great for quick touch-ups for restoring that ‘shaving’ edge.

    I would note that this (both the fine and extra-fine sides) is not necessarily recommended for setting the initial edge on a very dull blade. I’ve tried that before and it takes forever– you’ll want a coarser option for doing that. And you probably would want the extra-extra-fine (or a leather strop– not that I’m experienced enough to have tried either) for putting on the truly hair-splitting edge, but for all of my uses this works great.

    I’m not a professional chef, I don’t spend hours in the kitchen BUT I do like a sharp knife when I go slice a beautiful ripe tomato out of my garden or reach for my pocket knife. I’m not skilled at use of a regular sharpening stone– just takes too long. With diamond DuoSharp products I don’t have to spend hours sharpening blades— just a few swipes and and your done. I keep mine in the kitchen and every once in a while will make a few swipes over this nice wide stone and I’m done. Pocket knife need a touch up, few swipes and I’m done. If I go to the shop and need to sharpen chisle, rasp, scissors, etc- no prblem its highly portable. I’ll be getting a file for my chain saw soon and expect it will cut my sharpening time to a 1/4 with a better edge– quicker wood cutting on a long hot summer is the way to go.

    Golden Review Award: 2 From Our UsersFirstly, I purchased the product direct from USA via Amazon and it worked out half the UK price. It took only a week or so to ship the goods and the freight cost was very reasonable. The product itself is excellent. I bought it principally to sharpen professional quality cooking knives and this diamond whetstone produced very good results. The base is highly recommended as it includes rubber feet to stop it sliding on the worktop. Also it raises the whetstone to give clearance to your knuckles, when gripping the knife handle.

    Golden Review Award: 6 From Our UsersI have several Chroma 301/Porsche knives ( Chroma Type 301 Designed By F.A. Porsche 10 Inch Chef Knife P01 , for example), and they’re great. But keeping them sharp is kind of a pain because the only thing they tell you is NOT to use a Chef’s Choice-type electric sharpener. I bought a Japanese water stone, but they’re quite expensive, it arrived broken, and they’re not very easy to use or take care of. I decided to give the DMT DuoSharp Extra Fine/Fine a try, and it seems to fit the bill. I’d never seen this type of whetstone before, but it’s a good size to allow for long even strokes, it sharpens my knives quickly, and it’s MUCH easier to care for than the Japanese water stones. I agree with another reviewer who said it would be more helpful if they actually printed the grit size (fine or extra fine) on each side of the stone rather than the color-coded dots. Nonetheless, I suspect once I’ve gotten used to it, I won’t have to think about it.

    I had an old fine stone. Bought it in 1999, so it lasted quite a while. The new system has a much thinner stone. Put into the stand it is solid. Flip the stone over and you have another grit. I liked it so much I bought ex. course/course stone to go with it. The only thing I would change is stamping the grit number unto it instead of the color dots they use. I will do this myself with engraver–so I don’t need to be looking at the chart to see what grit it is.

    I was using a cheap pull through sharpener before purchasing this stone. What a difference!

    In a short time it revived my cheap kitchen knives so they were usable. I was also able to sharpen a newer Forschner Fibrox chef’s knife to an edge that was a little sharper than it came from the factory.

    I like it better than oil stones because you can sharpen dry on the diamond stone. I haven’t tried sharpening on waterstones yet to compare to the diamond stone.

Glad to have the pedestal base included, this makes it work well (knuckles hit the table otherwise, not enough clearance for your hand), I personally really like the larger 8″ stone for all sizes of knives, the 6″ version could work as well, the dual sides enable a person to get excellent fine honed cutting edge,of course a person could hone up to 12,000, but for everyday use, 2 thumbs up!!

    Golden Review Award: 17 From Our UsersI use this sharpener for my kitchen knives. Fine is actually rather coarse and it works super fast on a dull edge, and extra fine is fine enough that I can get away with no polishing. The sharpener needs a few drops of water and it cleans easily under water, the bench comes in quite handy. Highly recommended, much faster and less messy than your regular whetstone.

    Golden Review Award: 30 From Our UsersI had a DMT fine/medium and worked with hard Arkansas to finish. I decided to try a DMT fine/extra fine, and got this with the holder for a nice price on Amazon.

    This is a great setup. You can hold by the handle or set on a counter, and changing stones is quick and easy. What took me hours to do before DMT on aluminum oxide and hard Arkansas now goes very quickly, thanks to DMT.

    If it slows down a bit just put it under running water for a couple of seconds to wash off particles and it’s back. No need to hunt around for a source of good honing oil.

    I also like the tip finishing area at one end of the stone, which my first DMT does not have.
