You can't go wrong with Wusthof, I have been using them since culinary school 17 years ago. In fact I still have one chef's knife from the original set. They sharpen well and most important hold thier edge. Also good balance in your hand while working. I still use them professionally, and would recomend them. The Grand Prix line is also very good, I have them at home. Wusthof used to have a lifetime warranty, I don't know if they still do. I remember one of my staff somehow broke his knife in half,

he simply called the company mailed in the broken piceces and they sent him a brand new knife.
