PATINA ON CARBON KNIVES

---

What is Patina?

 Patina is an integral part of a carbon steel knife's identity, forming a protective layer that enhances both the aesthetics and longevity of the blade.

A patina is a thin, oxidized layer that develops naturally on carbon steel, helping to prevent rust and further oxidation. Unlike rust, which causes deterioration, patina acts as a shield, preserving the integrity of the blade. While patina can also form on stainless steel, it is less pronounced due to the presence of chromium, which adds corrosion resistance.

Over time, as the blade interacts with elements like salt, acid, water, and daily use, a patina will gradually develop. This process gives each knife a unique character while improving its resistance to rust.

It’s important to distinguish between patina and rust:

• Patina is a protective, natural discoloration that enhances the steel.
• Rust is a corrosive, reddish-brown layer that weakens the blade and should be removed promptly.

If rust appears, it must be addressed immediately to prevent further damage. Regular maintenance helps preserve the protective qualities of the patina while preventing harmful rust formation.

To maintain the patina and protect your knife:

• Wipe the blade regularly with a clean, dry cloth (even during use if needed).
• After each use, rinse the knife with lukewarm water and dry it thoroughly.
• Apply a light coat of food-safe mineral oil to prevent excessive oxidation.
• Store the knife wrapped in absorbent paper to help control moisture and protect the blade.

With proper care, your knife’s patina will continue to develop naturally, offering both beauty and enhanced durability.
