Amazing!  No other word fits.  This thing works so well you will be shocked.  I've had some old dull knives in my kitchen for years that I've tried to sharpen in in so many ways. No lie: three quick swipes on AccuSharp and these knives were as sharp as I've ever seen them! Though it doesn't work as well on serrated knives, it works better on serrated knives than anything else I've ever used--again it is amazing on standard Blades. I actually get joy now out of sharpening my knives because each time I do it I am blown away by how easy it is and how well it works. I have bought some for family members and friends (a perfect inexpensive present for anyone with a kitchen) and I cannot recommend the AccuSharp any more enthusiastically.

I even tried it on some dull razor blades I had lying around (cause I'm cheap and poor and didn't want to waste money on new ones) and after a few swipes they are almost as good as new--seriously!

Now, one note: For those of you who have extremely expensive knives this tool may notbe the perfect tool for you. I am no knife sharpening expert so I really can't say for sure. I know that this sharpener easily scrapes the metal to a sharp point but when I look closely at the edges of the blades that I've sharpened I do notice that the edges are not perfectly smooth. I'm assuming that a professional sharpening would perhaps get the blades equally sharp but much smoother, helping to prolong the life of your extremely expensive knives. But for the price and the ease of use this item can't be beat! I imagine that even for those extremely expensive knives this tool might be useful for the occasional light sharpening.  Awesomeness!
