DMT D8C 8-Inch Dia-Sharp Continuous Diamond Coarse

I’ve used this for hand-shaping and rounding soft metal and plastic parts which would otherwise get eaten by a power tool. Expensive but worth it.

Needed to sharpen my stones and this worked like a charm. I used w water. You always get what you pay fo

While it’s probably the best diamond stone money could buy, I would always recommend coarser stones for heavier work, especially on bigger blades and the supersteels of today!

This sharpening plate works great. I have several different sizes. Takes some time to break in. Ships fast.

Liked the thickness of the plate; good for flatening of stones.

Endlich scharfe Messer!

Billig sie die Platten nicht, abe jeden Cent wert!
Die Anleitung habe ich bei Youtube im Kanal von Schmiedeglut gesehen und dann hier auch von Schmiedeglut gekauft.
Der Versand ging super schnell! Gut verpackt! Danke fr die tollen Videos und den super Service! Weiter so!

Tipp: nicht zu fest drcken!!! Sonst knnen die Platten beschdigt werden!

Just got it a few minutes ago and broke out sharpening some of my knives. It is super easy to sharpen. It is flat and works super great. I am used to using japanese water stones, which also work great. But like many things, they need some attention before using, you have to soak them, then make sure they are flat and then you have to rotate them to get even wear, then flatten them again. Not too much work, but compared to these diamond “stones” the water stones are a lot of work.

This diamond “stone” is pretty much wet it and sharpen. Cause it is steel it doesn’t warp or wear away. Perhaps if you are really into abusing it, I think you could somehow hurt it. But barring anything that extreme, this stone will be flat, and sharpen your blades easily and effectively. Really just wet it and start sharpening. It’s that easy. Wipe it down and perhaps a coat of oil to keep it from rusting and you are done. I will say it doesn’t feel like you are doing anything until you feel the burr and it took half the amount of strokes to get there. Now if they made something with a higher or finer grit, I’m down to get that one too.

It is heavy so, don’t drop it. It probably won’t get damaged, but it will surely hurt you if it falls on you or perhaps your terrazzo tiles.

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 espectculo al percibir la uniformidad con la que estn distribudos los diamantes monocristalinos (los de mayor calidad).
Esta granulometra “Dia Sharp COARSE” denominado en la pgina de venta como “Grueso” es la adecuada para el vaciado delicado de cuchillos, antes de afilarlos con piedras de grano ms fino.
Yo la utilizo humedecida, aplicando muy poca presin, 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 despus 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 sintticas, 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.

You can find yourself in a Zen like state when sharpening your chisels and plane blades. You won’t rest until the edge will slice into paper at 90, and then find yourself looking for more things to sharpen. I have four DMT diamond sharpen stones, and they have almost changed my life. I am a much better woodworker for instance having really sharp tools. The courser DMT diamond sharpeners are fast, and will always be flat. The 1000 grit extra fine, and this 8000 grit extra extra fine sharpeners do not feel like they are doing much, but they makes a heck of a difference to how sharp you can get your edges. If I had just one tip, it would be to make sure you get a bur — usually with 400 grit in my case — before moving to the extra fine, and extra extra fine sharpeners. I have a rotary leather strop, but I have gone back to MDF with buffing compound and Brasso. (I use a 10X loupe to see if I have a bur or not). I also hone with the chisel or plane blade still in the guide, because I ‘think’ this prevents the edge being rolled over. The tools certainly do the paper cut test better with this methodology. One more tip — the roller on my sharpening guide had flat spots and did not feel nice to use. I turned a new roller out of plastic, and I swear this is doing a better job. It does not make sense, so it might just be that it is whisper quiet, but it all helps to get you into that Zen sharpening state. 🙂

I bought this Diamond Plate looking for an aggressive cutting stone to regrind the primary bevel on my chisel and plane irons. I’m impressed by how fast and well this stone cuts. I found it faster than my 8″bench grinder and easier to get consistent results as I can set the angle with the same jig I use to hone my irons after. Added bonus, it can be used to keep your water stones flat too!

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 was a fairly expensive item for sharpening a tool but it is a good value. I have had this for several years and my carving tools and planes have never worked so well. This item increases the value of all of your tools. Be warned…this is for final sharpening. If your tools are very dull it pays to start with a coarser grit or you will be working forever.

I bought my first dmt diamond sound a couple of years ago, and I have since phased out all of my old traditional stones. They are always flat, cut quickly, and leave a great edge. With the exception of a leather strop or the occasional polish on a translucent Arkansas, I don’t use anything else anymore. I have five different dmt products, and I have had zero issues with quality control or longevity.

I bought this product based on reviews, and at first was not sure if I was over spending, since I am a hobby woodworker. But once I received the product, I was pleasantly surprised at how well built it was. In fact, I was amazed how HEAVY the bench stone is! Indicates that the material is really solid and dense. With this, my sharpening system now consists of only two items: A regular Oilstone (coarse), and this diamond stone, and I get all my cutting edges razor sharp. (Off course, there is the trusty leather strop at the end, and for touchups).

The first one I recieved had a tiny imperfection (a bump in the casting) but Amazon returns are so easy I got a replacement within a couple of days. The plate itself is great and cuts really nicely. I used to use nothing but water stones but having to flatten them all the time becomes a real pain. These dimaond stones are worth the investment and I’ll be replacing my last two water stones once I have more funds.

What is there to say, these are fantastic. I bought this to lap my waterstones. It cuts but the stones and dull knives very fast.

It is a good sharpening diamond stone i use it to start my kife and also flat my stone.

This stone has cut sharpening time on badly blunted blades by at least 50% over water stones. Wish I had purchased it earlier.

I was a little apprehensive before purchasing this stone after the reports of it not being a true 3 micron 8K abrasive, that there were some larger abrasive diamonds in the mixture, and would require some “break in ” period before performing as an 8K stone. The stone arrived with a sticker that indicated that a break in session was done at the factory by DMT prior to shipping, as well as a note that indicated which side of the stone the diamond abrasive had been deposited. Good thing they tell you which side to use, because the bottom looks identical to the top. Don’t let that fool you into thinking they didn’t apply the diamond layer….it’s there! Reports are true….out of the box, including the factory break in, this is by no means a true 3 micron diamond plate. However, the level of refinement out of box is, by my guess, around a 2k-3k level or 6 micron. This is actually a very nice working edge with excellent slicing aggression as well as good push cutting ability. The more it’s used, the more it will wear in closer to the 3 micron rating. It has been my experience that the DMT EF 1200 mesh (9 micron) stone has the same issue….larger diamonds scattered in the mix and also needs a “break in ” period before it gives a consistent 9 micron finish. All of their diamond plates are extremely aggressive when new, and wear in over time with a better feel and better performance. Recommend a light coat of mineral oil during use with this stone, and the others. If you need a fast, efficient method of refining a sharp edge with wear resistance steels, this plate will work well, just keep in mind the initial limitations.

Effortless razor sharp edge. Work my way up through a couple water stones, then to the 1800 diamond, then this one. Works like a boss!

Works great. Bought course, fine, and super fine. The fine had some larger diamonds that caused bigger scratches. I think it just needs to be broken in.

I use the XX Fine with soapy water to sharpen scissors after I use the X Fine. Cleans up nice. I ordered and received this item in two days. Very happy.

Always my favourite stone to knock down any tool or mis-treated kitchen knife. Offers the most flexibility on-site tune up of wood working tools. Professional carpenter/tradesman and would not use any other brand than DMT. Prices have gone down since the last time bought it 10 years ago.

Definitely better than Chinese products. Would seriously advise to cut a 11 degree and 15 degree wedge on mitre saw to familiarize yourself with the knife angles most used. 20 degree angle would help register planer or chisel blades needing touch-up in the field. Fastest way to get the final edge on any metal or ceramic tool. For one that depends on sharp tools to do the final sharpening – the DMT line is a great asset to me

Great! Puts a far nicer edge on my knives than the traditional whetstones I have. It also does it far faster, and with less fuss. Add to that its being a similar price to a decent traditional waterstone of this grit, and it’s a no brainer to me.

It’s a lot heavier than it looks, and than I imagined it would be. I’m not sure why it is, but I like it, and it stops it moving about on the bench.

Excellent stone and does a fine job of putting the final edge on your knife, axe, or any other edged tool. With the 3″ width it really excels at sharpening larger kitchen knives like Santoku’s, Chef’s knives, Utilities, etc… If you don’t already have a stone holder or an elevated stone perch such as a piece of wood with a leather strip on top I recommend one to prevent the stone from slipping around and get it elevated. You will find this stone leaves a nice fine edge with just a slight bite to it which is good on a kitchen knife so that it can start its cut through things like tomatoes. I expect a long useful life out of this quality sharpening stone.

I have purchased the coarse, fine, and x fine versions from DMT and I have to say, these “stones” result in knives sharper than any I have been able to do before, by a long shot. Additionally, DMT’s service was on time – even a little faster than I expected, actually. Keep in mind these are not for novices, as one must have one’s technique (angle, stroke, patience, etc.) down pat or I’m sure results won’t be as fantastic as what I’ve experienced. But assuming you know what you’re doing, you will be able to get your bladed instruments as sharp as you could ever need – even moreso. I am going to end up with their entire collection.

Im a knife maker by trade and I love this stone..I fully expected some break in time because I know too many people who use this same stone..Thats just the nature of the beast. People also think that 8000 mesh means 8000 grit, IT DOES NOT..Learn your grits..Look at the microns. This stone will yield a “hazy” mirror edge polish when broke in. Though a mirror edge does not make a sharp edge, the apex does. I can shave paper and hair cleanly off the coarse stone… I produced a literally hair whittling edge of this stone(EEF) but it takes practice. Don’t give up because it doesn’t behave like you think its going to. These plates really shine on high vanadium alloy steels.

packing sucked-very heavy in bottom of a large box with paper on top. not impressed. second time its happened but noone cares. item is great-with patience and some skill-not alot this will put a great starter edge on a kitchen knife or bushlore knife. for kitchen its all you need-contrary to idea of a buffed edge. for finer finish use the finer diamond or cheaper use wet dry paper. excellent lifetime investment. unlike stones it doesnt wear.

My dad got his first DMT bench stone in the late 80’s, he’s still using it. So I decided to go this route as well after getting frustrated with water stones that wouldn’t stay flat for any length of time.

From what I’ve read and heard from DMT this will take some time to break in. The D8EE cuts fast and easily, not much pressure at all is needed. A little soapy water and a few strokes and you’ve got a very sharp tool to work with. I’ve only had this stone for a couple weeks but I have used it quite a bit (finish carpentry can be brutal on the edges of your hand tools). Despite there appearing to be a better polish on the bevel of my chisels with the extra fine duo sharp bench stone I find that the cutting edge seems sharper after I’ve used this stone. Basically it’s easier to shave the hairs off of a small patch of my arm or take light shavings off of end grain oak with the EEF sharpened blade than the EF sharpened blade. Not exactly scientific but I don’t have an electron microscope kicking around to check the blade out. This is an excellent stone that will only improve with age and use, without the hassles of water or oil stones. On top of the quality of this stone DMT customer service is fantastic!

I bought one of these stones and there was a small defect in the surface of the stone. My plane irons and chisels were catching on this defect so I called DMT directly. They asked me to send them the stone and they would examine it. But because I happen to live about 20 minutes from their facility in Massachusetts I asked if I could stop by. They said sure. So I went there and met Stan Watson (the guy in all of DMT’s videos), he took a look at it and found that it did indeed have a defect and replaced it on the spot!

DMT makes some fantastic made in the USA sharpening products and has second to none customer service!
