Review: Absolutely flat surface with diamonds imbedded in the surface - I have had a 8"x 2 5/8" DMT diamond plate in fine/extra fine grits and I really like using it to sharpen my woodworking tools, however, I needed a coarser grit to sharpen a damaged plane blade. I happened onto this 10"x4" DMT plate at a very good price at the desertcart Warehouse. I figured there wasn't much risk in a used diamond plate, since it is nearly indestructible. A bonus was that it came with a base. I love the 10" plate, where you can take a longer sharpening stroke which speeds up sharpening. It cuts aggressively and evenly. Diamond plates are also good for flattening waterstones and the 10" size is a bonus for that task. Review: Great Sharpening Experience - While I'm no sharpening expert I know a little bit about grinding and honing tool edges, primarily plane irons. Previously, the rough grind would be done on a grinding wheel attached to my bench grinder/polisher which did the job, not well, but OK. Following that I would hone the rough edge with sandpaper and water stone. I got tired of re-honing the grind on 80 grit paper which was a lot of work so I decided to try the DMT DuoSharp Bench Stone with coarse/extra coarse sides. What a pleasant surprise. The extra coarse side took off the old metal and created an excellent properly angled surface in less time than my grinder and the coarse side took the place of the 80 grit paper, again, in half the time. After the coarse honing I went back to 120, 240, 800, and 1200 paper before using the water stone, but each successive honing was much easier after establishing the original bevel with the DMT W250CXNB. It IS a little spendy but worth it If you do a lot of tool sharpening. You can spend the extra money and get a holder for the stone but it comes with a non-slip pad which works great so the holder isn't really a necessity. I was so impressed with this item I recently purchased the DMT DuoSharp Fine/Extra Fine stone for the next level. ## Features - Diamond Wet Stone: Crafted from the highest-quality materials and built to last, this precision flat dual-surface diamond knife sharpener stone ensures consistent, even sharpening every time - Coarse/Extra Coarse: Use the coarse diamond stone (45 micron / 325 mesh) to restore a neglected edge, or the extra-coarse diamond stone (60 micron / 220 mesh) for significantly damaged edges - Versatile: Engineered to provide cutting-edge performance, this diamond sharpener is ideal for sharpening virtually any knife or edged tool, including axes, hatchets, machetes, lawn and garden tools, and more - Fast & Easy: Micronized monocrystalline diamond surface sharpens edges faster and easier than a conventional knife and tool sharpener; No messy oils are needed either β€” sharpen bench sharpener dry or with water - Made In The USA: Preferred by professionals for their superior quality and versatility, our durable diamond sharpening stones are built to provide years of consistent performance and reliable service - Precision flat, two-diamond surfaced sharpener guaranteed to provide consistent, even sharpening every time - Two sided: Coarse diamond to transform a dull edge and Extra-Coarse diamond to repair a damaged edge - Sharpens knives faster than conventional stones with DMT's monocrystalline diamond surface - No oil is needed-sharpen dry or with water - Durable construction will provide years of consistent performance and reliable service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00004WFUL | | Best Sellers Rank | #193,738 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #366 in Sharpening Stones | | Brand | DMT (Diamond Machining Technology) | | Brand Name | DMT (Diamond Machining Technology) | | Color | Coarse / Extra-coarse | | Customer Reviews | 4.6 out of 5 stars 117 Reviews | | Global Trade Identification Number | 00017042003838 | | Grit Type | Coarse,Extra Coarse | | Included Components | Duo Sharp Bench Stone | | Item Dimensions L x W x H | 13.25"L x 4.5"W x 3.75"H | | Item Type Name | Bench Stone | | Item Weight | 0.54 Kilograms | | Manufacturer | DMT | | Manufacturer Part Number | DMTW250CXNB-BRK | | Manufacturer Warranty Description | Manufacturer Warranty | | Material | Micronized Monocrystalline Diamond | | Material Type | Micronized Monocrystalline Diamond | | Model Number | DMTW250CXNB-BRK | | Number of Items | 1 | | Product Dimensions | 13.25"L x 4.5"W x 3.75"H | | UPC | 017042003838 | ## Product Details - **Material:** Micronized Monocrystalline Diamond - **Brand:** DMT (Diamond Machining Technology) - **Color:** Coarse / Extra-coarse - **Product Dimensions:** 13.25"L x 4.5"W x 3.75"H - **Item Weight:** 0.54 Kilograms - **Grit Type:** Coarse,Extra Coarse - **Number of Items:** 1 - **Manufacturer:** DMT - **Global Trade Identification Number:** 00017042003838 - **UPC:** 017042003838 ## Images ![Diamond Machining Technology (DMT) W250CXNB DuoSharp Double-Sided Diamond Sharpening Stone, Coarse/Extra Coarse, 10 Inch - Image 1](https://m.media-amazon.com/images/I/61EAeFHJU0L.jpg) ![Diamond Machining Technology (DMT) W250CXNB DuoSharp Double-Sided Diamond Sharpening Stone, Coarse/Extra Coarse, 10 Inch - Image 2](https://m.media-amazon.com/images/I/91DYUrWwAcL.jpg) ![Diamond Machining Technology (DMT) W250CXNB DuoSharp Double-Sided Diamond Sharpening Stone, Coarse/Extra Coarse, 10 Inch - Image 3](https://m.media-amazon.com/images/I/917E4NRhBqL.jpg) ![Diamond Machining Technology (DMT) W250CXNB DuoSharp Double-Sided Diamond Sharpening Stone, Coarse/Extra Coarse, 10 Inch - Image 4](https://m.media-amazon.com/images/I/71iycDDkmJL.jpg) ![Diamond Machining Technology (DMT) W250CXNB DuoSharp Double-Sided Diamond Sharpening Stone, Coarse/Extra Coarse, 10 Inch - Image 5](https://m.media-amazon.com/images/I/71S5AJsZ5RL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolutely flat surface with diamonds imbedded in the surface *by L***N on October 25, 2020* I have had a 8"x 2 5/8" DMT diamond plate in fine/extra fine grits and I really like using it to sharpen my woodworking tools, however, I needed a coarser grit to sharpen a damaged plane blade.

I both a set of two that covers 4 grits. I use them with water, not oil. Unlike a stone, they don't end up with uneven ware out towards middle. You don't have to worry about moving the blade so that you can keep ipthe surface flat. I typically use sand paper glued on a hard flat surface to do my sharpening. And I loved that method for years. But the papers ware out, sometimes you get the edge so sharp that you end up cutting into the paper. I think I will still continue to use that method for Some things, but these are really quick to pull out and do a touch up on a chisel or a scraper. They are a bit expensive, but if you consider how much longer they will last compared to a stone, they are probably not a bad deal. I also used these to flatten the bottom of a #80 scraper plane. They worked great, with a little bit water, it took me 15 minutes to do the job instead of perhaps an hour that it would have taken with any other method. I recommend them. ## Frequently Bought Together - Diamond Machining Technology (DMT) W250CXNB DuoSharp Double-Sided Diamond Sharpening Stone, Coarse/Extra Coarse, 10 Inch - Diamond Machining Technology (DMT) W250CX-WB DuoSharp Double-Sided Diamond Sharpening Stone Bench With Base, Fine/Extra Fine, 10 Inch --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/2203645-diamond-machining-technology-dmt-w250cxnb-duosharp-double-sided-diamond-sharpening](https://www.desertcart.tn/products/2203645-diamond-machining-technology-dmt-w250cxnb-duosharp-double-sided-diamond-sharpening) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
