Diamond Machining Technology (DMT) 8-in. Dia-Sharp Whetstone Bench Stone, Extra Fine Grit Sharpener (D8E)

Excellent

Mine come with non-skid rubber feet. Everything is fine.

The diamond whetstone from DMT works great and fast, I love it. My only bad point that the box was miss one of the small Non-Skid Rubber Feet.

Tried yesterday, uneven surface, scratches and no rubber pads were provided as show in the pictures, some spots have high diamonds that causes deep starches and one side has ridges. Totally disappointed. Haven't expected that from DMT.

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.

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.....

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.

My stone had a manufacturing issue that I discovered after the return window had closet but DMT support solved it in an excellent way. I'm very happy with my stone and the support experience I had couldn't be better. Fully recommended!

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.
