## Questions & Answers

**Q: Medium-extra-extra fine is confusing.  So is there a coarse-exta-extra fine and a fine-extra-extra fine?  I doubt it.  So what is the medium part?**
A: Our extra fine is 1200 and extra-extra fine is 8000, so when the 4000 was put into production, it be came a medium extra fine to fit between the two existing extra fine grits.  Phew, that was a mouth full. Have a great day! Happy Sharpening!!

**Q: What are the dimensions of the stone (plate)?**
A: Size: 6" x 2" x 0.25" (152 x 51 x 6mm)

**Q: For kitchen knives and cutting knives, they are not Dull but I want to keep em sharp, what do I need? extra or extra2 or something else?**
A: We would recommend getting the Magna Guide. It is user friendly and comes with an aligner that will help you guide your knives while sharpening.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great and should last forever
*by R***E on February 26, 2025*

I am accumulating more and more DMT sharpening stones and I would recommend others to do the same. I started with a coarse and a fine grit which got my tools 95% of the way there. The coarse grit was used to set the angle and I polished it up with the fine. A few strokes on a leather strop and near razor sharpness. I bought an extra fine grit stone to see how much sharper I can make my knives. The point is that you can get really sharp blades with just one or two stones. I recommend the DMT stones basically because they work and should last a lifetime for the average user. They are made in the USA, come with great reviews, and I really like the results. I have lots of natural stones in my toolbox but modern steels can sometimes be difficult to sharpen and I don’t think I have used them in years. There is no question that diamond sharpening stones will sharpen any knife with a lot less time and effort, not to mention that you don’t end up with a huge mess afterwards.

### ⭐ Poor quality controls, and does not give a refined polish
*by E***Y on February 23, 2019*

I've been using various diamond stones, including DMT stones for about a decade. DMT used to be of the best quality, but lately I have noticed that their quality has been going downhill. When I received this stone, it had several small dimples on the diamond surface of the stone which caused the blade to catch as it was run across. I figured a good break-in would take care of it, but I was wrong. I found at least a couple of more spots on the stone which caused the blade edge to catch during sharpening, and resulted in actual damage to the edge. I sent it back to DMT, and the replacement was a little better, but still flawed. I got a refund, and decide to go back to water stones and Arkansas Stones. Boy, I forgot what I was missing. Yes, the diamond stones cut faster, but they leave deep gouges on the edge preventing a fine edge polish. A fine edge polish on any steel will literally double the longevity of its edge versus the toothy, micro-serrations of a diamond stone edge. I started putting razor edges on knives 30 years ago, and I have found that all types of bench stones have their place. I will save my DMT diamond stones for major profiling and steel shaping, water stones for most other edge refining tasks, and Arkansas Stones for extreme edge polishing so that it will shave the free standing hair off your arm without having to even press the edge against your skin to make the hair catch on the edge. So, in summary I do not recommend this stone. If you want the best overall sharpening system, get a coarse rated diamond stone for profiling work, a good water stone kit, a black surgical or translucent Arkansas Stone for an ultra edge polish, and then a good strop for final edge refinement. If I could only choose one system to save money, I would get a water stone kit and a good strop which will total less that $100..

### ⭐⭐⭐⭐⭐ My Go To Stones
*by A***E on October 14, 2016*

I've been using DMT products since the '80s. These Dia-Sharp 8" are my mainstays. Once broken in, they grade fairly and just don't require the maintenance of other stones. If you have the range (after the Medium-Extra-Fine I have them all) you can tackle anything. The 4000 (6 micron) has been a hole in this line for a while, it's nice to see it has been filled.As delivered, these stones have a lot of manufacturing "gunk" on them, and when new can be pretty sharp, i.e. grading lower (coarser) than marked. The stones break-in with use, and I actually break them in before using on anything of any significance.To break these stones in and clean them up, spray with 50/50 solution of Simple Green and Water. Use this as a lube for the stones all the time, it just works better than water or dry. Take a hardened piece (nice if it is the width of the stone) of 440C (I use a old knife tang) and run it up and down the stone, in circles or whatever, but try to cover the whole area. Keep adding Simple Green as needed, wipe the stone and steel off when it gets dirty (it will) and you should start to feel the stone smoothing out. There are little pieces of dirt and manufacturing eccentricities in the coating they put on them and you need to work that off. Once that is off, the stone will exhibit a much more uniform texture that you would expect. At the point that the surface is uniform, the stone will still grade a little rough, but will smooth out with use. Keep using the Simple Green solution to keep the stone and work clean. When breaking-in, pay significant attention to working the edges of the stone, this is important as this area can be a little rough. Even using the Dia-Lap 120 to chamfer the edges doesn't work all that well. If you are lucky enough to have a stone that they didn't get coated all the way to the edges, don't send it back; I wish they made them all that way. The stone should exhibit a uniform gray/silver appearance when properly cleaned and broken-in.
