As all our cutlery is made exclusively from high-quality 18/10 stainless steel, it is resistant to corrosion & acids. In the sophisticated method used to produce our hollow-handled knives, the handle & blade are made separately & then the blade is inserted into the hollow handle for perfect balance. The blade’s special steel guarantees that it will remain sharp for a very long time & cut superbly. All cutlery sets are suitable for the dishwasher (55 °C). Cleaning by hand is gentler, especially for knives.
