DMT W250EFNB 10-Inch DuoSharp Bench Stone Extra-Fine / Fine
The DMT Difference
Since 1976, DMT has been in business to do just one thing: make the world’s best diamond sharpeners. Product innovations such as our signature polka-dot interrupted surface, and others with our continuous surface of high-performance diamond, are praised worldwide for their superior quality.
From pocket-sized whetstones to heavy-duty bench stones, the difference arrives time and again through our undivided pursuit of sharpening excellence.
For DMT products, no oil or pressure must be used to sharpen the tool or knife.
Quality must be manufactured, not fabricated
Diamond Coverage differs widely from one manufacturer to the next. For long-lasting performance, DMT makes certain that each sharpening surface carries the most diamonds per square inch in the industry.
Diamond Uniformity is also key to sharpener performance. DMT uses a proprietary process that ensures near-perfect consistency in grit size. The result is a micronised monocrystalline diamond that covers evenly across the sharpening surface to prove effective with every use, year after year.
Beware of imitators!
Surface Flatness can mean the difference between a well-honed tool and one that is barely serviceable. Flat surfaces maintain consistent, even contact with the edge to produce a bevel that carries the same degree of sharpness from end to end. DMT sharpeners are engineered to be the flattest on the market, and built to outlast other products, which are variable in surface, and often warped, hollowed or grooved.
DMT Benefits
- The most diamonds per square inch in the industry
- Near-perfect consistency in grit size
- The DMT sharpener produces a clean, razor-sharp edge
- Best Surface Flatness

A most excellent tool.
This 10 inch benchstone is now one of my favorite tools for sharpening a blade.
I didn’t know what I was missing. it is extremely efficient. I am so glad I purchased it.
Get one.
I prefer diamond stones to natural stones. The diamonds cut fast and stay flat. I would prefer if the stone kept the same amount of bite as it had when new, but they break in and stay that way from then on. The fine/extra fine combo is nice for maintaining an edge. I really like the larger 10 inch size. It lends itself to doing a lot more than just sharpening knives.

Very durable.
This is the second DMT I have owned, I had the last one for 15 years until it got stolen along with my tool box.
Surviving 15 years as a joiners sharpening stone is testimony to its durability. If you want a really good diamond sharpening stone that will last a life time I reckon this is the one to go for.
Bought this with a plastic/ceramic angle guide (aka I have little to no skill) and with these 2 items I have been able to sharpen all my kitchen knives. Before they were all dangerously dull now wonderfully sharp. WARNING this thing come with manufacturing grit on the surface of the stone, that causes it to START as medium grit. This comes off after a few (4) knives then the true grit is exposed but overall right from the package it works great.

This sharpens all woodworking blades very quickly and easily to a fine cutting edge. One side is a coarse and the other is a fine grit. The large size allows it to handle larger cutting edges. I don't like the small size of the end tabs.

The 600-1200 stone is excellent for maintaining kitchen knives, especially 10 inch or longer ones. This is a nice big stone, with lots of area to work with. Unlike natural stones, it will remain dead flat. Removes metal very fast, so pay attention to progress and don't over-sharpen. If you stay on top of knife sharpening, only the fine side is needed. The DMT DuoBase is a good accessory for this stone.

Not my first Duo-Sharp. It performs as expected. Very good product.

Getting to like it more over time.
Previous stones blistered and shed their nickel matix in places leaving holes which led to blades catching and ripping even more out.
So far this seems to be an improvement. Price is certainly more competitive than prevously.
This is a general review for all 3 of the DMT 10-inch DuoSharp stones that I purchased. (I didn’t want to write three separate reviews)
These are the most excellent knife sharpening stones I have ever used. For the Coarse/Extra Coarse they cut through metal quickly and with very little pressure. Can profile a butter knife in less than 5 minutes.
For the Fine/Extra Fine it is no problem to polish the edge to razor sharp. Again, very little effort.
As to durability, well lets just say I have sharpened over 100 knifes, including an axe, a small sword, and a few exotic/specialty knifes and I don’t see any signs of wear at all.
I bought the black plastic holder for each stone (3) to minimize the risk of dropping/breaking the stones. For some of the larger knifes it is actually easier to clamp the knife/sword/axe down and hold the DMT stone and holder in the hand. I follow up with a leather strop for final polish, and the edges are hair popping sharp.
If you have expensive knives like i do it might not be for you
If you have expensive knives like i do it might not be for you, but I use it to sharpe my other knives.
It is easy to use and quick to get your knives to be sharpened. With the non slip holder this will be a life safer for your regular knife sharpening 🙂
My first exp w serious sharpening tools. Im very impressed at ease of use and overall performance. My knives have never been sharper and they feel like brand new tools aince putting on new microbevels. Although its easy to find the right angle Id suggest not starting w your fav blade. There is a bit of a learning curve. The larger size is great for axes and other large garden tools. In fact this makes me want to take the mower blades off and get them razor sharp!

This arrived in the mail this afternoon. Tonight I sharpened two chefs knives, a carving knife, and two paring knives very quickly. To be fair, the knives were not in bad shape but after a few passes over the stone and trues with the steel and they were all capable of shaving hair off my arm. The large surface area is great, much better than the 8" stones I've used in the past.

After paying this, I got rid of my 800 grit and 1200 grit water stones stay flat and do not have to be stored in water. Takes up a tenth of the storage space

It's a good "stone"
But – not as good as the hype.
I have found the trend stones to be more to my liking, although they are overpriced too. It might take a leap in technology before woodworkers and chefs have access to something that works the way we expect it too.
I have several trend and DMT diamond stones, and several stone “stones”. I know how to use them too.
I think competition might be our best friend here.
Quick and easy to use
I’ve never used water stones, but compared to using oil stones this is of course far cleaner, which results in me using it more often, which results in sharper blades, which makes it a great purchase. Super easy and super quick to tune up blades using the Red / Green stone, and paired with the Black / Blue stone I have also means I can completely re-angle a blade in about 5mins.
The extra-fine finish is good, but is still a bit coarse (doesn’t produce a mirror finish) but I’ve been happy enough up until recently; I’ve just found out DMT have just released an Extra-Extra Fine Dia-Sharp stone (Tan) and so have one on order right now. If that performs how the current DMT stones have I’ll have a very good setup.
This is the greatest sharpening "stone" that I have ever encountered. I first used my father's volcanic sharpening stone dating from the nineteenth century, and while it gave a keen edge, it had been worn out of shape. I tried various other "stones" of the stones variety with only middling success. And then I came across THIS. As they say: "There ain't not goin' back."

This stone is very easy to use, nicely made, and very effective on my very expensive knives. Easily used with water, is very fast to make a sharp edge, easily cleaned and easy to store in kitchen. This stone is far superior to all others I have tried - which are many. My only minor complaint is that I think, as superior as it is, the price is not reflective of a "fair" price for this item - although I understand the market decides.

This makes sharpening knives a breeze! The Extra-Fine/Fine works well. It takes longer on the first pass to get the edge than with a coarser stone, but not that much time. I like having the Extra-Fine to do the finishing. The diamond surface is fabulous for sharpening those hard blades that stones just don't seem to cut. I also like the large surface area that permits full strokes.

Recommended to me from on high, and it’s well that I took the recommendation. This product works, and does so without endangering the user. The knives get sharp in a hurry.

The fine extra fine did not dress the cutter down quick enough the coarse/fine did the job in a forth the time.

Excelle
Like all DMT Duosharp stones, this one is excellent. I have owned Duosharp stones for years and I ruined one by damaging a small portion of the surface due to my ignorance and when I mentioned this to the DMT customer service lady I was talking to regarding another matter, she said to send it in and DMT would replace it, which they did.
Great products, great company.
This works great! Lots of surface to work with which cuts the amount of time you take to sharpen a knife in half.

I’m a 25 year professional carpenter. I’ve seen, own or tried just about every sharpening system available. I’ve used this and the sister 10″ DuoSharp stone constantly for 20 years on the job site. This sharpener is small, lightweight, portable, requires no electricity, no oil, almost indestructible, short learning curve and quickly gives a scarey sharp edge. Quality isn’t cheap. Buy it once and you’ll never regret it.
First of all, let me say I’m a small-time knifemaker. I’ve used about every system of sharpening around, the “paper” wheels, the Lansky system, etc. They all work, but they’re a hassle and I’ve always been looking for something better. I’ve long thought about getting a DMT stone but haven’t had the money. I finally picked up the 10″ Duosharp fine/extra fine stone to give it a try.
It’s pretty much taken over all my sharpening needs these days. If a stone is reasonably sharp, not completely blunted or chipped, 5-10 strokes on the fine side followed by 10 or so on the extra fine put a good usable edge on a blade. Follow that with a little stropping and you’re 99 percent sharp. For a working knife, it’s all the edge you’ll ever need.
The size of the stone is great. I sharpen blades from 2″ to 8″ or so and it easily handles all of them. In addition, the size really seems to help with holding a constant angle, I’ve never been able to hand sharpen anywhere near as well as I can with this stone. Part of it is how fast it cuts, you don’t have to hold the angle for 100 strokes, just 5 or 10, part of it is the size of the stone.
Highly recommended if you’re serious about sharpening. It’s good to have a coarse stone around when you really need to reset an angle or clean up some chips, but this stone will move a lot of metal, don’t be fooled by the “fine” description.
This wet stone allows you to refine a knife edge with minimal effort. Notice that I said REFINE an edge. If you are looking to CREATE and edge or SET an edge, than you probably want a stone that has a much coarser finish to it. Try buying one of the DMT Extra Course or Coarse stones if that is what you desire. However, if you are looking to polish/hone an edge on your knife, this is the stone for you. Much superior to old school oil stones. Highly recommended!!!

Definitely worth the money
Over the years I have owned a number of bench stones. Most were given away because they just didn’t measure up. As a result, I spent a very long time agonizing over the decision before I was willing to drop this kind of money on yet another bench stone.
I am happy to report that I am dumbfounded. Compared to this, everything else I have ever owned was like trying to sharpen things with a wood rasp. Finally, I am getting the edges on my tools like I read about in the magazines.
This is a spectacular product well worth every dime I spent. It lives up to the hype. How often does one say that?
This stone is so good, that I decided to skip the water stone experience entirely and also ordered the extra-extra fine instead.
I bought the companion base for it. Also, worth the money…
This is a very good sharpening "stone" for not-completly dull knives, as the fine side will not remove much material. But a few strokes on the fine side and some more on the extra-fine side, you can get easy razor sharp edge.

The large surface is great for sharpening hand plane blades, and smaller blades as well. You won't be sad that you spent the extra for the larger surface. The dual grit works well. I purchased all 4 grits, (two stones) and sharpen all my hand plane blades, chisels, and router bits with these.

I have used this stone a couple times since I obtained it,
What a great way to sharpen your items. I need to get the
coarse/excoarse one as well.
Really like it. Got a blue/red stone, medium and fine I beleive, does a real nice job. Fast too. Really put an edge on a benchmade I was struggling with. Ordered a smaller very fine for finishing. WD

Gotta love i
You have to love it when you invest in one item that you randomly pick, and it turns out to be the last one you will ever need to buy.
I did a bit of research prior to buying – and it turned out to be the best purchase for the kitchen, after the food processor.
Now – some five plus years later – it still works like a charm, and all of my expensive knives are in topnotch conditions, thanks to this sharpening stone!
After buying any number of "pro" quality stones, sticks, machines and gadgets, I should have saved my time and money and bought this to begin with, I'd have saved a mint. With two sides I can do just about all I need without fear of burning, unless I want a polished edge.

Not much to say about a sharpening stone except that this is one of those tools that you don’t want to scrimp on. The DMT is well made and makes short work of chisels and plane blades, if I ever had to buy another stone, this would be it. Don’t forget the coarse/extra coarse stone, they complement each other.
I researched quite a bit before buying a stone & a steel and I am glad I did.
Oil Stones? forget em they are messy and not nearly as good as the Japanese water stones they wear down and they are slow.
Have a hardness of around 6.5-7 on the Mohs scale and on good knives that have a Rockwell hardness 56-60 and up to 66 they just dont cut it.
Water stones? these are good do a fine job, need to be soaked in water for a few mins, no mess but a good quality Japanese water stone will cost just as much if not more as this diamond stone and most are single grit, they also wear down rather quickly and become useless until you flatten them back out and what do you flatten them with? A big Diamond stone! or Aluminum oxide sand paper like maybe 120-220 grit glued to a piece of glass, which BTW makes a fairly decent sharpening stone on its own (in finer grits 800-2000) that are better than the oil stones.
These are made of Aluminum Oxide in a resin bond, aluminum oxide has a hardness of 9.2 (Mohs) these work better on good knives. These also need to be dried before storing them or they will deteriorate much quicker.
Ceramic Stones? These are good, dont need to be soaked and wont wear out as fast as regular water stones as they are in a “ceramic bond” instead of resin, these are either aluminum oxide or silicon carbide, the carbide is slightly harder at 9.5
These stones will still wear down just not as fast as the regular resin bond water stones.
Both resin bond and ceramic water stones rarely if ever come larger than 8X3″ (I have yet to see one, if they exist they would be even more expensive).
This is the only non-diamond stone I would recommend and even then just for a super fine 5000-8000 grit to hone & polish the blade.
Diamond stones? Well this is the only way to go as far as im concerned, no mess at all and if you use water on it the water fills in the pockets and the blade just glides over the stone and stays constantly lubed and cleaned.
These stones cut faster than any other stone have a hardness of 10 (Mohs) and stay flat these are perfect for good steel knives especially the 60-66 (Rockwell) hardness.
The 2 best features of these stones are they stay flat and they are 10X4″ which you just cant beat, it gives you nice long easy strokes.
Properly taken care of by the average home kitchen user just sharpening his/her small quiver of knives and in between using a fine steel this stone should last decades.
Using a fine steel everytime you use your knife you should only need to use your stone just a few times a year.
I would suggest this stone DMT 4″X10″ Extra Fine & Fine with the Duobase holder which makes it easier to use, then a fine steel like the “F. Dick 11″ Multicut Sharpening Steel” which I got here at Amazon also, using this steel makes a HUGE difference and keeps my knife razor sharp.
If you want the perfect polished razor sharp edge also get a Global Ceramic Whetstone, Fine Grit (5000grit) then finish it off with a “Leather Strop” glued to a wooden paddle with a bit of very fine metal polish like white jewelers rouge or flitz and you will have a truly razor sharp and long lasting edge.
This fine/extra fine whetstone is all that it promises & more. I bought it because of it’s large size to accomodate my kitchen knife collection. This whetstone gives me a razor’s edge, but I would suggest it’s use with a couple of other products:
1. The duosharp coarse/extra course whetstone
2. The DMT whetstone duobase to hold the whetstone securely during use
3. A mousetrap hone, because sharpening is NOT the same as honing.
Sharpening tools? Then Duosharp diamond whetstones are the way to go. They are much faster than conventional sharpening stones, are easy to set up and use, and clean-up in a jiffy, since only water is used in the sharpening process. I particularly encourage the use of the larger (4″ x 10″) stones, since they allow longer, straight strokes and a complete range of stone grades. By first preparing the tool angle with the Extra Coarse stone, then progressively using the Coarse, Fine and finally Extra Fine stone, you will easily get a sharp, ready to use tool. Enjoy!!
I purchased this item to sharpen woodworking planes and chisels. Good quality item. Works just as advertised. The larger size allows me to use a Veritas roller jig to keep the blade angle steady (although the jig is not worth the money for other reasons). Water wash off and easy cleaning. The plastic base is worth the extra money IMHO, but the antistick plastic mat works pretty well.
I also used the “scary sharp” system to put a razor sharp edge on the blades. This is a automotive sandpaper on flat plate glass. The DMT fine whetstone is about a 15 micron equivalent where the “sandpaper” goes down to 0.5 micron. The chisel edge shines like a mirror.
My only disappointment was in flattening the backs of old chisels. A coarser grade of diamond is needed for this higher metal removal technique. I tried coarse grade sandpaper, but it wore out quickly. The finer sandpaper grades do not because they only recieve 5-10 strokes after the diamond stone.
For knives and general sharpening utensils, this diamond plate is great. For woodworking, I would buy the coarse / x-fine combination whetstone. Use the coarse side for the one time flattening and the fine or x-fine side for the intermediate surface grinding. Keep one 9″x12″ glass plate of really fine micron sandpaper for the final polish.
I have used various stones for sharpening knives for (too) many years. In fact, I have reviewed two of them here on Amazon.com. I stand by my positive reviews of the stones, but this 4×10 diamond stone takes it all to a new level. I wanted to try the latest in whetstones, and this one caught my eye because it is LARGE, and has two grits built in. It is also very expensive.
That being said, using this tool will leave you speechless. It is that good. First of all, it is large enough to handle anything from a penknife to a 10″ slicer with full coverage in a single stroke. Every whetstone should be this size. It is also thin, and isn’t consumed during sharpening. The non slip pad provided with the stone works like a charm. Water is the only lubricant used, and cleanup is a snap.
Don’t be fooled by the “fine” and “extra fine” rating of it’s surfaces. The fine side will fix a badly worn kitchen edge in a few strokes. My guess is that the knife will also be better than new when you are done. The extra fine side will turn good steel into a razor in just a few more strokes. After years of taking time and care to acheive a perfect edge with natural and man made stones, this was an epiphany. The job was so easy, and the results so fantastic, that I went on a sharpening binge and turned over 15 well used knives into razors in little more than 30 minutes.
I also bought the Global sharpening guides for a couple of bucks. They are not needed for small knives, or for an experienced pro, but they make the fine edge look very uniform on longer blades. They give the “factory” look with the custom edge.
This is an incredible tool. By the way, when you are done, you just rinse it and put it away. I doesn’t get any better than this!
