Care Instructions for Tricolour Copper Damascus Kitchen Knives

Natural oxidation: Copper may darken or change colour over time when exposed to air. This is a natural process and does not affect performance or food safety.

Cleaning and maintenance: To maintain its shine, periodically clean the blade with lemon juice, rinse, and dry thoroughly. The citric acid helps remove oxidation and restore the original lustre.

Avoid moisture: Minimise contact with water. Always wipe and dry immediately after use.

The blade of this knife features a 12Cr18MoV stainless steel core, a refined alloy combining chromium, molybdenum, and vanadium for superior hardness (60 ± 2 HRC), excellent edge retention, and strong oxidation resistance. Surrounding the core, the 37-layer tricolour Damascus structure is composed of purple copper, brass, and 316L stainless steel, creating a visually stunning and high-performance pattern. The copper and brass layers add antimicrobial properties and a warm golden-purple hue, while 316L stainless steel ensures high corrosion resistance. Each layer is hot-forged under controlled conditions for perfect bonding, resulting in outstanding sharpness, balance, and long-lasting durability — ideal for both professional and home kitchens.
