I read a lot of favorable comments on the famous ceramic knives in general and I wanted to test once. Now I am the owner of these knives that supposedly sharp as razor blades. But I must say that each knife from my collection of various kitchen knives size better than these ceramic blades. I quite expensive knives as well as cheap and professional knives all really sharp as razors - provided sharpening from time to time.
Otherwise these Pradel knives are beautiful and keeps well in hand - but this is still insufficient.
It is better to invest in some traditional knives and a knife sharpener. Too bad.
