Die DMT Produkte sind Llgemein hochpreisig. Dafür funktionieren Sie sehr gut. Der Antrag ist sehr stark. Die Handhabung ist super.Ich hoffe der Stein hält für den Rest meines privaten Messerschleifer Lebens. Dann bin Ich voll überzeugt.

Good solid diamond stone that took a lot of abuse flattening sets of Narex chisels and new plane blades properly so I could keep them sharp on finer stones. Cuts nice and fast and keeps doing it, also great for flattening out your finer grit water stones with.

Tengo esta y tengo copias chinas, vale la pena pagar por esta aunque la uso principalmente como piedra de aplanado, algun que otro cuchillo ya vacie con ella, placa muy agresiva

I use three sharpening plates; the extra coarse, the fine and the extra fine. The extra coarse has quickly gone from too coarse to just right where I expect it to stay for a long time. About fifty years ago I was using oilstones. About forty years ago I switched to waterstones and they were a tremendous improvement. Recently I finally switched to diamond plates and I'm sorry I waited. They are a vast improvement over waterstones; far faster, much cleaner, and virtually no maintenance. The three DMT plates that I bought seemed virtually flawless. There is a very small bare spot on my fine stone, but it is of no practical consequence. I can't compare DMT quality to any other brand because I have tried no other, but I can say they are flat and effective and I hope they will be durable. Sharpening is no longer a chore, so now I keep my tools sharper than I did and of course that makes a tremendous difference in one's work. They are the best thing I've done for my woodworking in a long time.

Sharpening has three steps... 1. Getting the right shape/angle on the blade, 2. Sharpening to a very fine edge, 3. Honing from very sharp to extremely sharp.This extra coarse stone is great for shaping the blade. For example, I have a kitchen knife that was messed up by a grinder - the middle didn't touch the cutting board. In just a few minutes this extra coarse stone straightened the blade and got a good bevel along the length. It still needed to be sharpened with the DMT Coarse and Fine, but with the cutting edge of the blade straight and the bevel good, sharpening was quick and easy. Example 2. I have a 1 inch woodworking chisel that I had messed up on a grinder (bad angle). I had spent a huge amount of time (over an hour) with a coarse DMT stone getting it partially fixed - from a crooked 30 degrees to 28 degrees. Now that I have the extra coarse, I got it to the desired 25 degree bevel in minutes rather than hours. Yes, it took quite a while, but nowhere near as long as I had already spent doing the first part of the job with the coarse rather than extra coarse stone.Some of the other reviews said the plate was not flat. When it arrived I immediately compared it with my three other DMT diamond plates. The plate was flat (or I would have returned it). As I first used it, I could hear a slightly different sound the first time over each area of the stone. No surprise, it had to be broken in, so I made sure I covered the whole area. A couple small spots were still rough after the first pass, but were perfect after I ran the chisel I was sharpening over that spot 3 or 4 times. No big deal.Overall I highly recommend the DMT extra coarse for shaping a blade (kitchen or woodworking). Much less likely to mess it up than on a grinder (or in my case, I was able to fix the blade after messing it up on a grinder)The DMT regular coarse is excellent for the first sharpening - removing the scratches that naturally come from using an extra coarse stone. I originally got this coarse stone to flatten my waterstones - it does a good job of that, but is useful beyond just the waterstones, when I have to do serious sharpening work on a neglected blade.The DMT fine (there is no medium) does a great job sharpening kitchen knives (at least razor sharp), and taking my chisels etc to the next level. If I am just touching up a sharpening job, this is where I start. Kitchen knives rarely go beyond this level.The DMT micro fine was a disappointment for my chisels and planes. Instead I go to waterstones - 4000 grit then 8000 grit. Those give an almost mirror finish to the chisels. I called it a mirror finish until I got a 13,000 grit waterstone. Now that is my standard of sharp, for both the front and back of my blades.
