Query: A sharp, versatile knife

I use a knife frequently for food preparation. The one I had been using required frequent sharpening. While looking for a ceramic blade knife, I came across several positive reviews for Santoku style knives. This one seemed to be a good value. Since receiving this knife several weeks ago, I've used it daily - it's razor sharp and has yet to require re-sharpening.
