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

Not my first Duo-Sharp. It performs as expected. Very good product.
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.
Excellent. I also reviewed the DMT W250CXNB. That review has more detail.
Love this thing. I sharpen my chisels and knives to razor sharp.
great for any size knife, puts a fine edge and lasts foreve
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.
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.
The fine extra fine did not dress the cutter down quick enough the coarse/fine did the job in a forth the time.
This works great! Lots of surface to work with which cuts the amount of time you take to sharpen a knife in half.
Product works wonderfully, giving you a beatiful and razor edge with minimal effort, and the size accomodates even the biggest knives.
Easy to use, rejuvinated my kitchen knives and put a super edge on my buck knives. Not for use as backpack equipment but excellent to have in the house or workshop
Dmt sharpening stone is the best for all knives. It takes less than half of the time to Sharpen knives than other stones. I m loving it… But the only thing I can’t understand is he colors black and blue… It’s not easy .. But it is brilliant stone to have… Now I hv sharp knives all the time…
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.
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
