PVD, which stands for Physical Vapour Deposition, gives the objects exceptional colours and shades. It consists of the deposition of metallic particles through vaporization in a vacuum chamber. The coating is welded on an atomic level to the stainless steel, giving the material greater hardness and resistance to rubbing and corrosion, thereby preventing the formation of rust or oxides. Thanks to the use of non-toxic materials such as titanium and zirconium, PVD is also used in the biomedical field as scalpels or surgical blades. The monobloc knife is made as a single piece of steel. Compared to the hollow-handled knife, which consists of two parts, in the one-piece knife there are no gaps between the handle and blade. When you hold this type of knife, you get a pleasant feeling of solidity.
