Made in USA. Review: Works great and lasts a long time - 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. Review: Best choice if you only want one stone - I've used this for sharpening dozens of kitchen knives, pocket knives, straight razors, chisels, and planes to great success and for a while it was my only stone. At 1200 grit, it puts a fine enough edge on a blade for most knives and a serviceable edge on chisels (and maybe planes depending on what you're using them for). You may want coarser grits if you have chips in the blade, as it will take quite a while to grind out anything large or even moderately sized, and you will definitely want coarser stones if you are reshaping a blade profile, changing edge angle, or flattening chisels or planes. Similarly, you may want a higher grit for refining edges; I leave some knives at this level but go up to 4000-8000 on some, and higher still on planes and straight razors. It has held up very well and after many years and hundreds of sharpenings it still works great. You may notice staining on the surface, especially after using it on non-stainless steels and the grit can sometimes get gummed up, presumably from skin cell or oils from your hands. Usually, dish soap will do a good job cleaning it, but when I notice that it's not cutting as well I will occasionally use Barkeeper's Friend to really get the surface clean. It's a pretty harsh cleaner though, so I try to keep that to a minimum to avoid shortening the life of the stone. The biggest drawback to this stone is that I do think the feedback from the surface could be better, especially if you're a beginner to bench stone sharpening. It was my first bench stone and it definitely took me a while before I felt really comfortable maintaining an angle, reliably achieving a burr, and not goofing up my blades. Fortunately it's hard to do much damage at 1200 grit, but I do think that starting with a slightly coarser (maybe 600-1000 grit) water stone and a very cheap or even thrift-store level knife would be a better way to learn bench stone sharpening. ## Features - Superior Edge Maintenance: This knife sharpener uses a continuous coarse diamond sharpening stone to repair dull and damaged edges.

However, grit sizes can be confusing because of the different grading systems of the particles. Abrasives with the same grit number can actually have different particle sizes. It all depends upon the grading system. For example a 2,000 grit water stone would not have the same particle size as a 2000 grit wet dry paper. There is even a difference among the paper abrasives. The Europeans use the FEPA system. Their abrasive sizes are preceded by a P (e.g. P220). Americans use the CAMI system. CAMI just has the number (e.g. 220). Again identical numbers might have different size particles when measured in microns. Therefore, I always try to get a reading on the particle size in microns. A micron is 1/1,000th of a mm. DMT also makes Extra Extra Coarse which is a 120 mesh (thats 120 little openings per sq. in.) and particle size of 120 microns. Extra Coarse is 220 mesh and a particle size of 60 microns. The coarse grit is 45 microns. Fine is 25 microns. Extra Fine is 9 microns. There is also an Extra Extra Fine which is 8000 mesh that is a 3 micron particle size. > 50 microns is considered grinding material. 15 - 50 microns is honing material and less than 15 microns is considered polishing material. I hope this helps. **Q: Many of the reviews mention using this to flatten wetstones. Can I just use this to sharpen plane irons directly?** A: Here's the "what for" on this item You absolutely can sharpen any metal on this stone, but you will be limited to the actual sharpness and bevel width. This stone is made with larger diamonds than most coarse stones. Because of this, as well as its length and width (and skid-free bottom), it can take nicked and out-of-true edges and get them back on track very quickly (use water only, no oils). It is a 2X coarse blade, and awesome doing what it is intended to do (this includes grinding down chisels, whittling tools, whetstones, iron, steel, etc). It could be used to put a decent edge on your blade, but it really is limited to coarse work needed to prepare it for the proper stone; I recommend soft stones from Arkansas, they make great whetstones for fine honing, but any quality soft stone is the next step. To make this long answer longer, the reason the DMT is mentioned and recommended to flatten whetstones is that, again, the large diamonds go to work quickly and grind down uneven, pocked, or dipped anomalies on the much softer soft stones which makes plumbing a straight edge on a fine blade much more effective. So, basically, you keep the DMT to grind the soft stone to level, use it to work the blade to rid it of abnormalities, and then let that rejuvenated hard and straight blade make woo with that fine Arkansas (or personal choice of) whetstone (water, spit, and oil are optional). Sorry for the long story, take care of the ones you love, thank a vet, prepare, prepare, prepare, and have a great September; especially those of you who have the privilege of experiencing the changing of the colors! Also, it's the time of year we wait for; muleys, white tail, wapiti, antelope, and turkey (plus whatever else ya'll get to hunt and stock in your territory). Prep them blades, clean and sleep with them guns, shake them cartridges to loosen up and distribute the powder, and keep field stones handy for quick edges for the cold, morning, field dressing...And thanks for the question! **Q: is this 3 stones in one package or just one? because the picture is three stones.** A: You only get one but they show the 3 different grits. These aren't stones but rather diamond embedded steel plates. **Q: How flat is it? Is it flat enough to true up a waterstone? To put it another way, can it be a smaller/cheaper version of the DMT lapping plate?** A: Its very flat I use the coarse and extra coarse to flatten water stones all the time. I would recommend them to anyone for just water stone flattening it works great but in also use it to sharpen with great results ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great and lasts a long time *by K***Y on March 6, 2025* I own 4 DMT diamond stones.

One Gerber has been with my for over a decade. Over the last few months, I have realized how I have completely neglected blade care all this time. I use them purely for home use, work use, and have yet had a chance to use them as an "outdoorsman" would... someday! Some of my knives have gotten nastily damaged and dulled over the years.... some just dulled. I have a "pro" motorized, ceramic kitchen knife sharpener, and out of of desperation I TRIED using it on my oldest Gerber. Nope, can't barely fit the thick blade in the slots, and even so, the original bevel must be at too large of an angle. It looks like it tried to grind down a secondary bevel. I know that it cuts at 20 degrees. After research, watching sharpening methods using everything from sandpaper, to whetstones, to splash & go stones, to diamond bench sharpeners, I settled on this one for all my general sharpening. After trying to emulate the methods I had watched, I cannot believe it, but I already have had HUGE results! My oldest most damaged Gerber, pitted, dulled, etc.... After doing the work 10x slower than anyone else, I managed to restore the edge, get ride of the pitting AND properly sharpen the blade all on this stone... Didn't even use a coarser stone before hand to "repair the edge"... I got it to the point that it cuts through paper smoothly, through the full blade with no jagged tears... I do not have a proper way to strop the bevel off yet, so I did some horizontal blade sharpening pulls, alternating until the bevel pretty much was gone, and I used my work mat in place of a leather strop in the meantime until I can get one... It can't arm hair shave very well just yet, but I am sure until I can get more of the proper gear to remove the bevel and I work on my technique, I am convinced I will be able to get to that point. I watched a video of a guy sharpening a blade on this stone, and had such good technique, was able to shave his arm hairs straight away. I will get there! Meantime, fantastic bench stone! DO NOT BUY CHEAP DIAMOND STONES! Those are not made properly where the diamond is not ionized into the metal, and are just stuck on with adhesive, meaning it will wear down and rub off completely over time. This stone will last for years in comparison! ## Frequently Bought Together - DMT D8C Dia-Sharp Diamond Knife Sharpener, Coarse Diamond Sharpening Stone, 8-Inch - Diamond Machine Technology (DMT), 8-in.
