Technical Features of Coltellerie Berti knives:
- They may be forged (plastic processing under heat) or laser cut (cold cutting of the blade) but the blades are always a single piece
- The steel used is made in Germany (X50CrMoV15 by Krupp) and has a high carbon content, conferring a high cutting capacity and duration. The steel used to make high quality knives is not 100 % stainless, since perfect stainlessness diminishes cutting capacity. This is stainless steel which can be washed, even in a washing machine, but it can be stained. The best way to keep them perfect is washing by hand followed by immediate drying.
- Tempering involves both heating at 1055 °C and super-cooling at -80 ° C to ensure that the cutting capacity lasts the longest possible time.
- Handles are made of natural materials – horn or boxwood – or else of plastic. Plastic materials however are hand processed from a slab and not moulded.
