Well, we finally broke down and replaced this wonderful knife. The knife we are replacing is the exact same model that we purchased in 1991. I am able to sharpen the other 9 or 10 of the Zwilling knives of that same vintage but not this one as the serrations are too small and have been unable to find a professional knife sharpener locally. As to the knife it is wonderful and one of the top 2 favorite knives we own (the other is the 6" chef's knife). It is perfect for slicing bread, tomatoes and other foods that are best cut with a serrated blade. The fact that we bought the same knife twice says it all.
