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!
