Amazon.com Product Description:
The DMT W250FCNB 10-Inch DuoSharp Bench Stone offers the finest in sharpening technology. Double sided, with both fine and coarse diamond surfaces, this stone is capable of handling a wide variety of edges with industry-leading precision and accuracy. This innovative stone offers a multi-patented sharpening surface that features a convenient dual-sided design for sharpening. The stone's hard wearing surface and durable design guarantees that it will provide consistent, even sharpening for years to come.
Versatile Sharpening
With the DMT 10-Inch DuoSharp Bench Stone, sharpening has never been easier. Use the fine diamond stone (25 micron / 600 mesh) to get that razor sharp edge, or take advantage of the coarse diamond stone (45 micron / 325 mesh) to easily restore a blade's neglected edge back to its original performance. 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 long chef’s and carving knives, woodworking tools and much more.
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.
Compact Design
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.

- Finally - - A tool that does the job
I have spent over the years more than a few dollars looking for a sharpening tool that is easy to use and does the job right.
The DMT Dual 10-inch is finally the one - I am glad the search is over.
Easy to use [ once you practice and get the movement right - recommend that you practice on old knifes first before you attempt sharpening your $200 chef knife ]
Gets the job done in only a few minutes.
I have used it on Kitchen knifes, expensive damascus ... Read More

- Why did I wait?
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, Id 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.

- DMT diamond sharpener
Fantastic product. Beats sharpening stones hands down.
I will purchase the extra fine/extra coarse stone soon.
Would definitely buy the base to go with the stone.
Its about 4" wide which makes it useful for plane blades.
