Keeping Your Knives Rust-Free: Three Effective Methods

Even the best knives can succumb to rust, especially those made from carbon steel or those that have a low chromium content, which are more prone to corrosion. But don't worry—rust doesn't mean your knife is ruined. You can restore your blade's shine with a few simple methods. Here are three effective ways to remove rust from your knives.

Understanding Knife Rust

Rust can develop on any metal surface exposed to moisture and acidic substances. While minor rust spots are not harmful, they can be unsightly and, if left untreated, can compromise the knife’s cutting edge and safety.

Preventing Future Rust

Keeping your knives rust-free is crucial for their longevity and performance. Here are some tips to prevent rust from forming:

• Always dry knives thoroughly after washing.
• Store knives in a dry, low-humidity environment.
• Apply a light coat of tsubaki (camellia) plant based oil to the blade as needed, especially if the knife is not used frequently.
