keeps knifes sharp
I've been using the DMT FWFC DuoSharp Double-Sided Diamond Sharpening Stone for a few weeks now, and Iโm really impressed! It makes sharpening my kitchen knives super easy and efficient. I love that itโs double-sided, so I can switch between grits without any hassle. Definitely a must-have for anyone looking to keep their knives in top shape!

Dull knife, you say?
You know, I did quite a bit of research before I purchased this little dandy. I read the reviews of all the stones, the various diamond sharpeners, the whole bit. Additionally, I looked into the "guides" and anything else to simplify the sharpening process. By no means am I a knife/survive in the wild/kill a tiger just by looking at it kind of guy. However, this sharpener was easy, fast, and efficient. If you have questions about appropriate technique, look up a youtube video or check on the dmt website--easy as cake, and a blade as sharp as you could need. I purchased the coarse/fine one (red & blue), but I figure I'll pick up the extra fine some time down the road. Now, for the breakdown: Pros: 1) Compact--the sharpener folds into the handles (which you already know, by now)and it's double sided. 2) Effective--a gently, consistent motion gets you blade just where you need it. The instructions with this sharpener state that it should only be used for camping/hunting knives, etc., but I took the kitchen knives to task. A couple of them were so dull that I could run them across my finger with no consequences. Now, I don't dare. The knives cut through paper and cut tomatoes (and other veggie sundries) with ease. Just maintain a consistent angle and motion, and you should be fine. Not rocket science. 3) Efficient--My kitchen knives took a bit longer (for the reason, see #2), but everything that had a reasonable edge took less than 2-3 minutes. If your knives are real garbage you may want to start with the extra coarse, but I'm too cheap right now. Time was a factor, and this beauty delivered. Cons: 1) On the coarse side, the diamond coating was missing along one small section of the edge. I know, I know, it really doesn't matter in the least, but I'm just kind of particular like that. That's it. Ecstatic about my purchase, will never look for another sharpener! Good luck!

Great sharpener!
The sharpener is awesome, the handle is super flimsy and fragile. This should have a thicker plastic for the handles, everytime I pick it up to use it I'm afraid the handle is going to break. If I took this hunting it would surely break!

A Good Double SIded Sharpener
This DMT sharpener is a nice, useful double sided tool. The plastic handles do seem a bit flimsy; time will tell if they hold up to regular use. Some plastics are quite tough.

I Expected Better From DMT
The handle is extremely cheap, don't cover the center of the stone. If you apply pressure with your blade, it flexes. The older style handles felt more durable. I would buy one of those instead, and leave this lesser model. The flex is annoying, and on a sharpener this size is unacceptable, especially from DMT. It does sharpen well, like every stone from DMT does. I expected better, and I do not recommend this product for the money.

Perfect General Sharpening Stone
If you're only going to have one stone for keeping a handful knives sharp, this is probably the best product you're going to find. This is what I recommend to friends and family when they invariably ask me what to get after I sharpen their knives. What this product isn't: a professional bench stone for getting the best edge you can. If you're working on professional chef's knives or woodworking tools, get as large a bench stone as you can and learn to use it. DMT also makes fantastic bench stones that will generally work more quickly and consistently than other brands. What this is: A professional diamond sharpening surface in the two most useful grits for general use. - You use the blue (coarse) side to remove bulk material. This is perfect for knives that need a lot of attention due to nicks or extreme dullness. It can also be used to correct or change the blade bevel on smallish knives. - You use the red (fine) side to finish up what you started with the coarse side. Several passes on each side is all you should need to create a nice lasting edge. How to use: Take care to ensure that what you're sharpening is parallel to the surface of the stone. It can be tricky at first, but you'll feel the increased friction when the diamond surface has contact with the blade. Otherwise, you'll just be scraping the edge of the stone along the blade and doing little sharpening. This is one of the great advantages of a full-size bench stone. You can use it wet or dry; I prefer to sharpen by a sink to rinse the stone and keep it lubricated with water. It just makes things faster. For knives, hold the blade at a 22 degree angle to the stone (halfway from perpendicular is 45, and halfway from that is 22.5) and move in the direction the blade is pointed. Sweep along the blade as you sharpen to get the whole blade in each pass. On one side, you'll be pushing the blade away from you, but to get the other, you'll need to pull it toward the handle. This is a little dangerous, but if you use a little caution it should be fine. If you need to remove a lot of material, feel free to move the blade in circles and really grind the metal off. Once you're close to the final edge, start making lighter and more 'graceful' passes, being sure to alternate the sides every couple passes. This will ensure that you won't get any burrs or roll the edge over.

Good tool, works well.
This tool works very well with the coarse side rapidly removing enough metal to restore the proper shape. Then the fine side works well for a sharp edge. Seller delivered promptly. The handle is not as robust as an earlier diafold that I owned and eventually wore out after many years of work.
