DMT D8F Dia-Sharp Diamond Knife Sharpener, Fine Diamond Sharpening Stone, 8-Inch

Very good quality Precision cut

This is the best sharpener I've ever owned a period I bought six of them all the way from extra course to extra extra fine. If you want to sharpen your knives properly these Diamond Stones are the way to go not the cheap pull through types. Those ruin your blades these are professional grade. If you like sharp knives or whatever reason either in the kitchen or for personal protection I recommend this highly

So I have had a few lock-back pocket knives kicking around my life for a few years now. 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!

Every DMT stone I have gotten with the exception of the course has had significant quality control issues. Unfortunately, this one was no exception. There is significant grit contamination on the stone. (See pictures) I broke it in by sharpening about 5 or 6 kitchen knives I do not care about and made sure to get all of the loose diamonds off. Even after the break in period there is significant grit contamination. You can feel and even hear it when you pass over it with a knife. With that being said, it is still a good stone as long as you are not super concerned about grit progression and wanting a mirror polish (even then you can likely get the scratches out with a finer stone). It is a well made stone with significant weight to it and will undoubtedly last for years and years if you take care of it. If it wasn't for the grit contamination, I would definitely give it a 5 star review. It cuts fast, funny enough faster than even my DMT coarse stone, I think. I really like DMT stones despite the lack on outstanding quality control. They are good stones that will last forever and are well worth the money.

Good quality product. Sharpens the knive really fast

I heard about this stone from the YouTuber OUTDOORS55. Listen first off, I'm terrible at sharpening had to get me a angle guide. I'll day this though, this stone is insane. It'll sharpen your super steels and leave them with an insane edge. Warning after sharpening you may end up cut a limb or finger from the sharpness. I jest, but I just thought I should warn you. Bye reader!

Use 6" course to shape knife edges then 8" fine to finish edges. Use mostly for kitchen knives and does great. Study and manage the sharpening angles for a super edge.

Just got this stone today. My ultratech was getting pretty dull so I decided to give this a shot after watching videos that recommended this exact stone. I was afraid when I saw the bad reviews about it not being fully coated or flat. Mine is only missing the diamond coating on maybe a 1/2mm square on the very very corner so I feel like that is more than acceptable. And from what I can tell it’s perfectly flat. It cuts into the steel very well and it doesn’t cut so fast that you would be afraid to remove too much material so I really like that. It sharpened m390 just fine and after stropping the blade it whittles hairs. As does my 154cm Emerson that I just sharpened on it. And let me say I’ve abused that knife every way possible and there were decent chips in the blade that I was able to work out. I’d recommend this stone with a two sided strop and 3.5-1.0-0.5 micron diamond stropping compound. I’ve been able to get knives to shave with simple cheap stones but those edges don’t feel nearly as sharp as this Diesharp stone makes them. Overall I’d buy again. And it’s very heavy so it doesn’t slide around even with decent or light pressure applied. I’m sure this will last me a good while and I like that it’s low maintenance because gosh do I hate oil stones.
