Made in USA. Review: Scratchy to use - The dmt mef is scratchy to use even with lube, and he scratch pattern is harsher than the sharpal 1200. It will produce a burr and a sharp edge. After using it further I believe it has quite alot of grit contamination and would return it if possible..... Review: My Go To Stones - I've been using DMT products since the '80s. These Dia-Sharp 8" are my mainstays. Once broken in, they grade fairly and just don't require the maintenance of other stones. If you have the range (after the Medium-Extra-Fine I have them all) you can tackle anything. The 4000 (6 micron) has been a hole in this line for a while, it's nice to see it has been filled. As delivered, these stones have a lot of manufacturing "gunk" on them, and when new can be pretty sharp, i.e. grading lower (coarser) than marked. The stones break-in with use, and I actually break them in before using on anything of any significance. To break these stones in and clean them up, spray with 50/50 solution of Simple Green and Water. Use this as a lube for the stones all the time, it just works better than water or dry. Take a hardened piece (nice if it is the width of the stone) of 440C (I use a old knife tang) and run it up and down the stone, in circles or whatever, but try to cover the whole area. Keep adding Simple Green as needed, wipe the stone and steel off when it gets dirty (it will) and you should start to feel the stone smoothing out. There are little pieces of dirt and manufacturing eccentricities in the coating they put on them and you need to work that off. Once that is off, the stone will exhibit a much more uniform texture that you would expect. At the point that the surface is uniform, the stone will still grade a little rough, but will smooth out with use. Keep using the Simple Green solution to keep the stone and work clean. When breaking-in, pay significant attention to working the edges of the stone, this is important as this area can be a little rough. Even using the Dia-Lap 120 to chamfer the edges doesn't work all that well. If you are lucky enough to have a stone that they didn't get coated all the way to the edges, don't send it back; I wish they made them all that way. The stone should exhibit a uniform gray/silver appearance when properly cleaned and broken-in. ## Features - Sharpening surface accommodates range of edges- from large knives to small pointed tools - Medium-Extra-Fine diamond to refine a razor edge - Sharpens knives faster than conventional stones with DMT's monocrystalline diamond surface - No oil is needed-sharpen with soapy water - Durable construction will provide years of consistent performance and reliable service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0094TMPOM | | Best Sellers Rank | #116,798 in Kitchen ( See Top 100 in Kitchen ) #30 in Knife Sharpening Whetstones | | Brand | DMT | | Brand Name | DMT | | Color | Gray | | Colour | Gray | | Country of Publication | USA | | Customer Reviews | 4.1 out of 5 stars 56 Reviews | | Global Trade Identification Number | 00017042007409 | | Grit Type | Extra Fine | | Grit type | Extra Fine | | Included Components | DMT D8ME Medium-Extra-Fine Dia-Sharp Bench Stone, 8" | | Item Dimensions L x W x H | 16.5L x 8.9W x 35.6H centimeters | | Item Type Name | Medium-Extra-Fine Dia-Sharp Bench Stone | | Item Weight | 839 g | | Item weight | 839 g | | Manufacturer | Diamond Machine Technology (DMT) | | Manufacturer Part Number | D8ME | | Material | Diamond | | Material Type | Diamond | | Model Number | D8ME | | Number of Items | 1 | | Number of Packs | 1 | | Product dimensions | 16.5L x 8.9W x 35.6H centimeters | | UPC | 017042007409 | | Unit Count | 1 Count | ## Product Details - **Material:** Diamond - **Brand:** DMT - **Colour:** Gray - **Product dimensions:** 16.5L x 8.9W x 35.6H centimeters - **Item weight:** 839 g ## Images ![DMT Diamond Machining Technology (), 8-in.

So is there a coarse-exta-extra fine and a fine-extra-extra fine? I doubt it. So what is the medium part?** A: Our extra fine is 1200 and extra-extra fine is 8000, so when the 4000 was put into production, it be came a medium extra fine to fit between the two existing extra fine grits. Phew, that was a mouth full. Have a great day! Happy Sharpening!! **Q: What are the dimensions of the stone (plate)?** A: Size: 6" x 2" x 0.25" (152 x 51 x 6mm) **Q: For kitchen knives and cutting knives, they are not Dull but I want to keep em sharp, what do I need? extra or extra2 or something else?** A: We would recommend getting the Magna Guide. It is user friendly and comes with an aligner that will help you guide your knives while sharpening. https://www.amazon.com/DMT-MAGKIT-4-Diafold-Magna-Guide-Case/dp/B00HZ3SCEQ/ref=asc_df_B00HZ3SCEQ/?tag=hyprod-20&linkCode=df0&hvadid=312003160272&hvpos=&hvnetw=g&hvrand=13279394980127448932&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1014863&hvtargid=pla-421920059749&psc=1 **Q: what is this d8me model, I can find no mention on the manufacturer's website, I'm assuming this is the same as the d8e?** A: Diamond Machining Technology (DMT) ## Customer Reviews ### ⭐⭐ Scratchy to use *by T***B on 17 November 2024* The dmt mef is scratchy to use even with lube, and he scratch pattern is harsher than the sharpal 1200.
