Review: This thing indeed does work. - The item works pretty much as I expected and I received what I ordered. What I learned after I received it, was this was a fine grit diamond tapered rod and that course grit and medium grit Diamond Serrated Sharpeners were also available from DMT. Though I did accomplish great results on my serrated knives, the task may have been quicker with a courser grit. Long story short I Got R Done!
Review: top quality, perfect for serrated blades! - We had picked this up to sharpen some serrated knives that just weren't cutting it anymore (ha!). We were pleased to find that the taper on this sharpener allowed us to dress multiple sized serrations, and it brought the blades to a razor sharp level. There had been chips in the serrations, and those have been refiled and sharpened to the point that you would never know they were an issue. This thing really does its job well. An excellent product that I would purchase again!

### ⭐⭐⭐⭐⭐ top quality, perfect for serrated blades!

### ⭐⭐⭐⭐ Super Fine Grit.
*by A***N on February 20, 2014*

The grit on this sharpener is extremely fine. It is almost non-existent. If you're planing on really sharpening or reforming edges, this is not the proper grit. I would recommend the fine 600 grit, or even the coarse 325 grit for general sharpening. This 1200 grit is more for polishing edges after sharpening with a more aggressive grit. Personally, I find this sharpener useless for sharpening serrated edges, but it will put a fine polished edge on an already sharpened blade. It makes a nice addition to a full set of DMT sharpeners, but if you're only going to buy one for all purpose use, I recommend you get the fine 600 grit diafold. The quality of the product is excellent, and the design is great.
