Review: Great little sharpener - This sharpener works great for quick touch ups to get a good working edge and is small enough to store anywhere. (Hunting pack, tackle box, etc) This sharpener is not intended for you to sit down and sharpen an entire kitchen set so keep that in mind this is more of an on the go sharpener.
Review: 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.

### ⭐⭐⭐⭐⭐ Dull knife, you say?
*by L***R on February 22, 2012*

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!
