I had three ceramic knives from Rosenstein and Söhne. One of them is me been dropped because of improper storage and blunted. Another tip she has lost due to improper use. In addition, the blade has solved over time as well as from the wood holder, what I did not find so pleasing. Only the smallest third knife has remained intact. So this purchase of ceramic knife sets, while a knife block as well-intentioned restart can be seen, hopefully better 'ends' or my knives brought a longer retention period. Cutting with ceramic knives applies indeed as particularly beneficial to health because the ceramic fibers of the plants probably less damage than metal knives. Overall, I feel it but sharp as less (even if often something else is said), perhaps because the blades seem to me thicker. The wooden handles are kept very simple and should be oiled from time to time, because they are otherwise brittle, are no longer look so beautiful and touching.
