The cutlery is coated in metal using the PVD method which uses vacuum deposition. It’s a method of decorative surface treatment that has been used for decades in the watch and jewellery industries and, being completely food-safe, it can also be used on cutlery.


· Production Technology: PVD = Physical Vapour Deposition. The coating is applied using vacuum deposition, which means that articles with hollow cavities cannot be coated (e.g. hollow-handled knives). The various colours are the result of different chemical compounds in the coating.

· Thickness of Coating: approx. 0.8 μm (Micrometres): Experience and tests have shown that a thickness of between 0.5-1.0 Micrometres guarantees the best adherence of the coating and is therefore ideal for daily use. To compare: 30g silver-plating = 12-15 μm (Micrometres). Despite its hardness, the coating does not prevent scratches or signs of wear.

· Special Tips:

Owing to technical limitations, hollow-handled knives cannot be PVD coated (see Production Technology).

Coated blades can leave marks on porcelain. Use porcelain cleanings products to remove marks.

Coated blades cannot be re-sharpened.

· Care and Cleaning:

PVD cutlery is dishwasher-safe.

DO NOT machine polish!

When cleaning by hand, do not use any abrasive materials as they can scratch the surface.

Fingerprints will be left on the surface after use. To remove these, simply use a polishing cloth or rinse with hot water and rub dry with a kitchen towel or cloth.
