DMT D8C Dia-Sharp Bench Stone - Diamond Knife Sharpener for the Workshop, Jobsite or Kitchen - Coarse (325) - Flat Diamond Sharpening - Non-Slip Knife Sharpener- Made in the USA - 8 x 3 x 0.38 Inches

I own 4 DMT diamond stones. Unfortunately, everyone I have bought before this one has defects. I am happy with this stone though. My extra coarse stone is missing diamond coverage all along the edges and has a big blotch missing in one of the corners. My DMT fine stone has extremely bad grit contamination that you can not only feel, but can hear, when sharpening. So, I was happy when I finally got a DMT stone that didn't have grit contamination and has complete diamond coverage including along the edges. It is unfortunate that it took 4 stones to get a good one. To say DMT's quality control is subpar is an understatement. I kept seeing good reviews and so thought maybe I was getting lemons, just a random bad one. But no. Everyone stone except this one had significant defects. That being said.... even with the defects the stones work well enough and will last. I know it's odd to say so much negative and have a 5 star review. That is simply because this stone was exactly what it should have been. No grit contamination, no missing coverage and a great stone. It cuts fast and leaves a uniform scratch patter. It is well built and will last year's making it a great buy for $50. If you can get a DMT diamond stone without any significant defects, then you're getting a good buy. These stones will last for a very long time if you take care of them and can cut any steel type including super steels like s110v or s90v.

I now have four diamond sharpeners. Three of them are DMT with this being the most course, all the way up to Extra Extra Fine 8000. It is perhaps ironic, but this plate (I never know whether to refer to DMT sharpeners as plates, stones or sharpeners) is proving to be one of the most useful. It can reprofile something like a 1" chisel from a multifaceted and rounded disaster, to a beautiful flat bevel in less than five minutes. It really eats metal, and like all diamond stones, it doesn't clog up. I use Window cleaner btw. I gave it four stars for value, but that should probably be four and a half as it was a lot less money than the DMT fine stones. Durability is looking like a three stars as I can see places where I am wearing through the diamond coating. You need to be careful with the outer edges, and not use it with slightly rusty metal, like restoring old planes for instance. All in all though, my DMT sharpening experience has been incredibly positive. My tools are far sharper than ever before, and you would not believe how nice a big kitchen knife feels to use after honing down to 8000 grit. I do actually use a motorized leather strop that I made to finish off with green buffing soap.

This is my third DMT Diamond stone. I made the mistake of purchasing a “bargain brand” of the same description, but I quickly learned that I had made a horrid mistake. DMT really makes great stones…I do lathe work for a living, and I use these to keep my skews razor sharp. It is quick and easy to pause in the middle of a lathe turning (when my chisel is becoming dull), an touch up the edge on this stone with a bit of water. In like 45 seconds, it’s done and my tool is again cutting with smoothness and precision. Yes, these stones do wear out…yes, every time you use it, it loses a bit of “cutting power effectiveness”, as the Diamond bits slowly wear off of the surface. But hey, that’s to be expected, as nothing lasts forever. But I can tell you, these last a long time for my uses, and when they become worn/cumbersome, I just order another one and I’m happy! I find that one of these 8” DMT stones last me almost a full year before I finally admit that it’s time for a new one. Not a bad price for a year’s service, and I literally use it daily.

I wanted a diamond stone that could do triple-duty as a japanese waterstone flattener and knife repair type work, maybe even scissors or other household items. This stone seems to fit the bill but it did have some rough spots or raised diamond flecks that gouged-up my softer 5000 grit waterstone when new. To break in this DMT stone I ground off the the broken tip of an older chef's knife and used another smaller diamond stone to polish off the edges of this stone. It seems pretty uniform and OK for use on my waterstones now. Use caution if you decide to attack this diamond stone with another diamond stone in an attempt to speed up the break-in process. The edges of my new DMT coarse stone are now a bit too smooth and polished. The stone has lost its bite in those areas and I am unsure if it will return in time with use. Aside from the few aberrant rough spots out of the box, this DMT coarse stone isn't as coarse as I thought it would be. It produces a not-too-rough toothy edge that is appropriate as a final edge on some of my knives that I like to use for tougher chores. This 325 mesh DMT stone seems like a good compromise for people who want a diamond stone that can multi-task like myself.

You cannot beat a DMT stone. The dimensions make sharpening really easy. Just remember - you must go through the neessary stages. It doesn't sharpen just by virtue of beinng a diampnd stone. If necessary, postpone your purchase of a stone until you can afford a good one. Bare minimum stones I'd go with are 220/600/1000 on 3x8 backing. If you're a woodworker and use a lot of hand tools which require sharpeneing flesh out and add stones as you learn from the ones you're starting woth. The people agt DMT are knowledgable, and quite helpful.

Solid diamond sharpening plate. I use it to level whetstones. Definitely aggressive brand new. But very effective.

This is a good tool for sharpening your chisels, plane irons, etc. It is durable, well made and as flat as advertised. I thought it was supposed to come with plastic, anti-skid feet. Mine didn't so I put some stick-on foam rubber pads and they work nicely. It is low profile so you might want to elevate it an inch or so to avoid dragging a chisel handle on your bench when you abrade the burr off of the back. You'll need to use a lubricant in order to help your edge tool move smoothly and carry away the abraded metal particles. DMT sells a solution to do this. I'm sure it works great and it is probably safe. However, I use vegetable oil. After use I wipe the plate clean with a paper towel to prevent oily grime build up. I suppose you can use a spritz of water but that will make the steel rust. This is not the first DMT product I have owned. The quality is reflected in DMT's prices but they are not outrageously expensive.

Very disappoint with this purchase because: 1) There is a hard, pin head size bump 2 3/4 inches down from the top and 7/8 inches from the side of the stone. This defect reduces the usable flat surface to less than 2/3 of the original stone size. This bump is hard enough to damage my chisel tip. See the picture where the pick is pointing at. 2) Seems to be a used stone. The four corners are shiny but the rest of the stone has dark strikes 3) The package is missing the 4 non-skid rubber feet mentioned in the 3rd bullet item of "Above this item". Will be returning this stone and go to a Woodcraft store to inspect and pick up a new stone instead.

Very good quality sharpening solution. I use it to sharpen plane irons and chisels and I've not seen the slightest sign of fatigue after several months of use. Guaranteed flatness, and no need for lapping... ever. To use, all that is needed is a small amount of liquid to lubricate (the manufacturer recommends water -- glass cleaner is another option with no adverse effects), then sharpen, then wipe off the slurry (the swarf is sign that it's working). The plate is quite heavy, but it helps keeping everything in place while sharpening. Let it dry and store it away. easy. I've found I can obtain results faster by applying very little pressure -- no need to force weight down into the stone to sharpen. There is a small break-in period, after which I started getting bluish halos (photo attached). It's a tell-sign cleaning is due, which can be done easily by a good scrubbing with a toothbrush and some kitchen/sink cleansing powder agent (such as calcium carbonate and sodium carbonate). The surface can also reportedly be cleaned with a high-polymer eraser. Even easier! Very responsive support from the manufacturer. Very satisfied customer! The prices for the coarse, fine, and extra-fine stones fluctuate somewhat, I'd recommend setting a watch.

Pessoalmente acho muito agressiva para usar diretamente nas lâminas, pois remove muito material. Estou usando para retificar minhas whetstones da King e da Suehiro e para isso essa pedra diamantada é fantástica. Nunca consegui retificar minhas pedras usando lixas e outros métodos mais baratos então resolvi arriscar. As pedras diamantadas da DMT não são baratas mas valem a pena. Retificou minha King velha de guerra, que acumulava uma barriga considerável depois de mais de 10 anos de uso. Como foi necessário desbastar muito da pedra demorou um pouco (quase 3 horas de trabalho). Mas ao final o trabalho ficou ótimo e a pedra diamantada ainda estava como nova. Recomendo.

This is the best bench stone for sharpening anything! Thick and perfectly flat forever!

Las placas diamantadas DMT son las mejores del mercado. Si se les da un uso inteligente duran toda la vida. Vistas con una lente de aumento, son todo un espectáculo al percibir la uniformidad con la que están distribuídos los diamantes monocristalinos (los de mayor calidad). Esta granulometría "Dia Sharp COARSE" denominado en la página de venta como "Grueso" es la adecuada para el vaciado delicado de cuchillos, antes de afilarlos con piedras de grano más fino. Yo la utilizo humedecida, aplicando muy poca presión, con mucha paciencia. Nada de hincar con fuerza la punta del cuchillo hasta que salten los diamantes por el suelo. Como cualquier herramienta con diamantes, al principio "come mucho material" y después es cuando ya coge su ritmo de trabajo. Al terminar, lavarlas con agua y secarlas con un trapo limpio, esperando que haya perdido todo rastro de humedad antes de guardarlas en su caja. La planitud de la placa es tan buena que se puede utilizar para lapear (rectificar) las piedras de afilado, ya sean naturales o sintéticas, siempre con agua. Por supuesto, no comparar estas placas con similares muy baratas que venden en sitios chinosos on-line. Afilar un cuchillo es un arte que hay que hacer con mucho mimo.

Attention le modèle est vendu comme une X-Fine, mais c'est en faite une "Coarse", gros grain... Pas la même utilisation...Retour à l'envoyeur..
