With the DMT 10-Inch DuoSharp Coarse / Extra-Coarse Bench Stone, edge restoration has never been easier. Use the coarse diamond stone (45 micron / 325 mesh) to quickly and easily restore a neglected edge, or take advantage of the extra-coarse diamond stone (60 micron / 220 mesh) for edges that are significantly damaged. Simply place the DuoSharp Bench Stone on any flat surface, and its non-skid rubber mat will keep it firmly planted during sharpening.
The extra-large diamond surface allows the DuoSharp Bench Stone the ability to sharpen virtually any knife or edged tool, including axes, hatchets, machetes, lawn and garden tools and much more. In fact, the DMT 10-Inch DuoSharp Bench Stone's versatility is seemingly endless.
Its ease of use is equally impressive. You can ditch the messy oils that are required with other sharpeners, and the innovative diamond surface allows you to easily sharpen dry or with water.
Innovative Diamond Surface
DMT's patented DuoSharp surface provides unparalleled performance thanks to its monocrystalline diamond surface, which sharpens faster and more efficiently than other sharpeners. This allows you to spend less time sharpening edges and more time actually using them. DMT uses only the finest materials for their products, and all of their products are made in the USA.
The 10-Inch DuoSharp Bench Stone measures 10 x 4 x 0.38 inches (LxWxH), and it weighs just 1.5 pounds. Its compact and lightweight size make it easy to take anywhere.

From the Manufacturer
The DMT Difference
Diamond Uniformity, Coverage, Surface Flatness
Uniformity: DMT uses micronized monocrystalline diamonds, precisely sized for a more uniform diamond surface. No other diamond sharpeners offers micronized monocrystalline diamond and most offer the lesser grade poly-crystalline diamond. Mono-crystalline is like an ice cube made up of one particle holding its form while poly-crystalline is like a snow-cone made up of many small particles that get sheared off during use.
Coverage: DMT’s process assures the most diamonds per square inch in the industry providing a more durable sharpening surface.
Surface Flatness: DMT bench stones are engineered flat, assuring even contact with the knife or tool.
Choice of Diamond Surfaces
Interrupted or polka dot surface for which DMT is famous has slightly recessed holes that will collect metal fines (swarf) removed during sharpening to prevent loading. Fast sharpening action; not recommended for pointed or very small tools.
Continuous surface presents a more conventional looking sharpening surface. Fast sharpening action; able to use on small surface edges.
HardCoat, DMT’s newest proprietary surface, is able to withstand the rigors of ceramic sharpening, providing an even longer service life to the sharpener.
DMT is committed to providing the best diamond sharpeners in the marketplace. If the sharpener is found to be defective, we will replace it.
Benefits of The DMT Difference
- Precise Diamond Sizing for Consistent Sharpening and Longer Life
- Best Diamond Coverage for Longer-Lasting Service
- Flat Surface for Even Sharpening
- Choice In Diamond Surfaces
- DMT Commitment- Replacement If Found To Be Defective

DMT offers an assortment of very portable, hand-held sharpeners that provide easy storage in home, shop, truck, back-pack or RV. Made to sharpen an array of knives and tools while portable enough for on-the-go sharpening. Interrupted surface models include Diafold, Mini-Sharp, 4” Diamond Whetstone; continuous diamond surface stones include 3” Credit Card Style, 4” stones and Mini-Hone sharpeners; one Double Sided Diafold is available in the HardCoat diamond surface, designed to withstand the rigors of ceramic knife sharpening.
Most steels are designed to align a knife’s blade, but DMT diamond sharpening steels in 10-, 12- and 14-inch models will both align and hone the blade. All are continuous diamond surface but one 12-inch model is offered in DMT’s HardCoat diamond surface, specifically designed to withstand the rigors of ceramic knife sharpening. For those who wish to sharpen with ceramic, DMT offers a 12-inch ceramic steel sharpener.
Bench / Counter Stones
DMT offers a nice selection of diamond bench stones from 6- to 12-inch lengths of varying widths to accommodate home, sport and tactical knives along with a mixture of DIY and woodworking tools. Models include interrupted, continuous and one DuoSharp model in HardCoat diamond. Models include Diamond Whetstone, DuoSharp and Dia-Sharp bench stones.
If you are unsure about sharpening, try one of DMT’s sharpening systems to assist with proper sharpening angles. All systems revolve around the 7-angle adjustable blade guide utilizing either 4” diamond whetstones in the Aligner models or Double Sided Diafold Sharpeners in the MagnaGuide line. The blade guide can also be used with DMT’s bench stones.
For best sharpening results keep diamond stone clean
Care and Use of DMT Diamond Sharpeners
All models are designed to be used dry or with water so there are no messy oils and extensive clean up to worry about. Always clean the DMT sharpening surface after sharpening. One option is to use a high polymer eraser to remove any residue, especially useful with cylindrical styles like Crystal Saver and Steels. Another is to simply rinse the surface with water and wipe dry. After several sharpenings, clean more thoroughly with a mild abrasive and brush; rinse surface with water and wipe dry.
Always put away dry and store in a dry environment. Use leafing (paper towels, cloth, plastic storage bag) in between your bench stones to prevent abrasive sides from rubbing.

- Clean and Wipe Dry
- Store Dry
About Sharpening with DMT
Get the Most out of your DMT Sharpener
There is a ‘break-in’ period for your diamond stone. Initially, it will feel especially rough but will smooth over time without impacting performance. Let the diamonds do the work; just light strokes with the edge to sharpen, same number of strokes each side. Approximately 5 or 6 strokes per side (depending upon condition of edge) compared to 30 strokes per side on a conventional stone, saving time and extending the life of the knife or tool. Start with a coarser grit for damaged or dull edges and work to finer grits. The work the edge is to do will help you determine the grit needed: Rough work, end with coarse grit (cutting cardboard); finer work, work through finer grits (food preparation).
- Initial break-in
- Light strokes to sharpen – let the diamond do the work
- Faster than conventional sharpening methods
- Rough work – coarser grit
- Fine work – finer grit

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!
They are very easy to prepare with just a few squirts of distilled water. (Buy the black plastic base too, by the way. The little rubbery mat they come with is a poor substitute. The base keeps the plate very stable. It also adds some elevation, which makes a world of difference when you're trying to flatten the back of a plane blade or, especially, a chisel without rounding over the edge. It may seem cheap that they don't include the base but... trust me, just buy it.) These plates are also easy to flush, clean and store. These are MUCH better than the big ceramic flattening bricks whose pores get clogged up with gunk, and they're much faster and less messy than aluminum oxide sandpaper.
Also, buy the big 10-inch Duosharp plates, not the smaller versions. If you feel a need to justify the cost, figure out the cost per square inch of cutting surface; regardless, the larger ones are just much more versatile and easier to use.
A few other things I've learned about these plates over the past 10 years or so that I've used them:
1. You CAN wear the diamond grit off trying to do heavy metal removal, such as flattening the sole of a new plane. As always, let the tool do the work and if it doesn't do the work, you may be using the wrong tool.
2. These plates are NOT the best tools for grinding a new bevel, and certainly not for honing a fine edge on your best handtools.Read more ›
I purchased this diamond stone to true the water stones and it does a great job, rendering them flat with just a few strokes. The added bonus was that I also used the diamond stone for the first stage of regrinding the chisels; it was much faster than the water stone and stayed flat during the process.
Unless you have a method of securing the diamond stone to your bench, get the available holder, its definitely worth the money.
I did notice a bit of rust forming on the steel substrate after leaving it wet, so I now dry it off after each use.
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).Read more ›
