DMT D8C Dia-Sharp Bench Stone, Diamond Knife Sharpener, Coarse (325), Flat Sharpening, Non-Slip Knife Sharpener, 8" x 3" x 0.38"

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 have many DMT sharpeners. Very handy and reliable item. Nothing to complain about.

It's a very good diamond plate. I bought it to flatten my Naniwa Chosera and Suehiro sharpening stones. I've used it about 25 times, and it still maintains its original characteristics with no signs of wear yet.

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.

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.

As I mentioned in other reviews for this company’s products, these diamond blocks are super high quality and do a fantastic job on a knife edge. A little bit of a learning curve for cleaning and using but I absolutely love these things. Don’t be scared of the price, these things are worth every penny. Awesome product!

The media could not be loaded. I was really hoping for a high-quality sharpening stone, especially at this price point. Unfortunately, what I received was a huge letdown.I ordered the 325 grit diamond stone, but the entire working surface is covered with large, rough inclusions. They’re embedded so firmly that they don’t come off even when scratched with a fingernail — some are just massive. These inclusions completely ruin the sharpening experience and make the surface unusable for any kind of precision work.Here’s part of the product description:“Diamond Whetstone Knife Sharpener: Assured not to hollow or groove, our precisely engineered knife sharpeners ensure consistent, even sharpening every time...”This is simply not true. The surface is uneven and unpredictable. Instead of sharpening evenly, it’s more like dragging your knife across gravel.Pros:• Might be useful for sharpening an old, rusty axe — if you’re feeling adventurous.Cons:• Extremely poor surface quality• Misleading product description• Not suitable for fine or even medium sharpeningFinal verdict: This could have been a decent stone, but the execution is terrible. If you’re okay with throwing $50 away — go for it. Otherwise, steer clear.

All of them are awesome especially if you’re new to sharpening and you are learning.
