Damascus steel with 36 layers of purple copper, brass, and 316L stainless steel, core in 12Cr18MoV steel, and octagonal sycamore handle
Care Instructions for Tricolour Copper Damascus Kitchen Knives
-
Natural Oxidation: Copper layers may darken or change colour due to air exposure. This is normal and does not affect performance or safety.
-
Cleaning & Maintenance: To maintain shine, periodically wipe the blade with lemon juice, rinse, and dry thoroughly. Citric acid helps remove oxidation and restore appearance.
-
Avoid Moisture: Minimise contact with water; always clean and dry immediately after use.
Blade Construction
The blade features a central core of 12Cr18MoV stainless steel, enriched with vanadium for high hardness (60 ± 2 HRC) and excellent edge retention. Surrounding the core are alternating layers of 316L stainless steel, purple copper, and brass, forming a total of 37 layers (18 on each side plus the core). Purple copper enhances aesthetic contrast and absorbs minor impacts, while brass adds golden tones and smooths hardness transitions between metals.
Hot forging in a controlled atmosphere ensures perfect bonding, followed by vacuum tempering and stress-relief to optimise microstructure, toughness, and reduce the risk of cracks. Final 15° per side sharpening and chemical etching reveal the authentic tricolour Damascus pattern, producing a sharp, durable, corrosion-resistant, and visually striking blade.
