Diamond Machining Technology (DMT) Diafold Serrated Diamond Knife Sharpener, Fine (FSKF), 4"

I have this Diafold "Serrated" Knife sharpener in the Fine and Coarse diamond grits, and has thus far been very impressed with the quality of these sharpeners.I originally bought this with just the task of sharpening serrated knife edges in mind, but this sharpener has turned out to be more than just that. First, for the serrated edges - I have two Sypderco knives (Police, Delica) that have a combo serrated edge, and between this and the coarse grit, it works very well on re-honing the edge on the serrated VG-10 edges. Due to the VG-10 being a little more difficult to sharpen, your method has to be steady and you have to stick with it on the fine grit to get a nice edge.For the serrated knives in the kitchen - most of my kitchen knives are much softer and easier to sharpen than the Spyderco serrated edge - so after sharpening the Spyderco's the kitchen knives were a breeze. I used the coarse to get the edge started, then moved to this fine grit to finish it off.Where this sharpener came in handy and as a surprise is when I discovered how well this works on my small pen knives, pocket knives and mostly woodshop tools. It is perfect for pen knives and small pocket knives for touching up an edge - the size of the rounded rod is perfect for control and for small edges. Also, in my woodshop I use exactor knives and other carving / cutting tools that have curved edges For instance, Lee Valley makes a small carving tool with replaceable blades of different shapes / contours - like curved, sloped, straight blades - and these Diafold rod sharpeners turned out to be PERFECT for this application. I have also employed this tool in some of my plane restoration projects when there are tight spots that need a little filing or honing.The uses for this tool seem to increase daily. For instance,I wanted to touch up the edges on my electric hedge trimmer - again, tight spots without a lot of clearance and small edges to sharpen on the hedge trimmer - and this tool again shone in that application.Nice tool, highly recommended if you have any applications like serrated, tight spots, small edges, etc. I own many DMT tools, and the quality does not need to be justified - that is one thing you can rest assured of, that the quality is there.Thanks for reading.

If you're like me, you read all the recent reviews (I give no credence to old reviews, regardless of Amazon sorting). This thing is awesome for sharpening serrated knives. I want to dispute some things negative reviews have stated. The handles are easy to open on the ones I received. And who cares - if you don't like it, send it back. The other main complaint from people is the diamonds rubbing off. It's possible there was some bad plating at one time, but not now. If you use it correctly, with essentially no pressure (never use pressure with diamonds), follow the instructions (read them!), or look at other websites that explain in much more detail, you will have no problems. Diamonds are so different than other sharpening methods that you have to discount reviews from people who haven't used them before, even if they claim to be experienced - they may not be experienced with diamonds. They work. Use as directed. I do hate the handles and would gladly pay double for nice ergonomic (not even retractable) handles. A nice round wooden handle would be better. I can't ding a star because of the lousy handles because the price is right for what you get, as it is. I'm sharpening Cutco serrated knives which have this ridiculous "D" serration. All that does is try to ensure you use them for sharpening (and buying more knives). Even the micro-serration on the cheese knife is no problem for this sharpener. Multi-level marketing at its worst. They are great knives, but go ahead and sharpen them yourself. Re-profile them with these DMT sharpeners. It takes very little work to fix them up. Use diamond plates for the non-serrated knives. We love our Cutco knives, but have now resorted to sharpening them ourselves. Definitely do not use the Cutco sharpener. That is a total waste of money.

This DMT Diafold Sharpener is a good tool that comes in a convenient package. As other people have stated before in thier reviews, the folding plastic handle does feel thin and reletively flimsy, but I do get the impression that it will stay intact for some time if treated with care. This is my first sharperner specifically for sharpening the serrated areas of my knives. It works well and didn't take long to perform the technique properly. I wish the file/sharpener was a little longer with a more gradual taper, or if they made it with more than one file/sharpener that was a different taper or thickness. Other than those suggestions for improvement, this product works great.

Up until recently, I have been sending out my serrated knives to a service when they needed sharpening. I got the fine diamond blade which is all you will really need if your serrated knives are not too dull to start with and it will get your blades back to factory sharp in short order. It is easy to use and works on serrated knives as well as scissors, vegetable peelers and the like. Do not be surprised by the size or the price, this tool is serious and will give you years of solid use.

Excellent all purpose sharpener. Works well for all sizes and styles of knives that I have. Lasts a long time, this is a replacement for one I got ten years ago.

It was difficult to open both handles and about the fifth or sixth time I opened them, the center part that holds the cone split in half. It was very clear that the center part was made from two pieces that were bonded or seamed together around the threaded end of the cone. I pushed out the pins holding the handles to the middle part, removed them, glued the two halves back together, then very slowly screwed the cone back in and put the handles back on.I considered rating it 1 until I glued it back together. It seems to be holding together and the handles are a little easier to open than before. The sharpening cone works great. Probably the best at sharpening serrations I have used. It's very sad that the middle part split, so I rated it 3, but it would have been 5 otherwise.
