Carbon Steel & Knife Care

Why Carbon Steel?

High carbon steel is my go-to choice for crafting knives. Known for its hardness and edge retention, carbon steel holds an incredibly sharp edge longer than many other types of steel. Plus, it’s easier to sharpen, so you can keep it performing well with just a bit of care. However, this strength and sharpness come with some specific care needs, as carbon steel is not stainless. Due to its lack of chromium, it’s more prone to rust and staining, requiring a bit more attention to maintain.

Over time, your carbon steel knife will develop a unique patina, which is a natural dark layer that helps protect against rust. This patina is a sign of a well-used, well-loved tool, with tones of blue, gray, and sometimes even purple. It not only adds character but also tells the story of each knife’s journey and use.

Caring for Your Carbon Steel Knife

To keep your knife in peak condition, here are a few essential care tips:

  1. Hand Wash Only
    After each use, wash your knife with warm, soapy water, and dry it immediately with a soft towel. Avoid using steel wool, which can scratch the steel. Never put your knife in the dishwasher, as the harsh environment can cause rust and damage the handle beyond repair.
  2. Prevent Rust with Oiling
    To maintain a clean, protective surface, use food-safe oils like mineral or camellia oil on both the blade and handle. These oils help prevent rust and add a layer of moisture protection to the wood. Apply a small amount, wiping away any excess to keep it from feeling greasy.
  3. Storage Tips
    Avoid putting a wet knife into any sheath, especially a leather one, as it can trap moisture against the steel, leading to rust. If you plan to store your knife for an extended period, clean, dry, and oil it thoroughly before storing it in a cool, dry place outside the sheath.
  4. Handle Maintenance
    Keep the handle dry, especially if it’s made from wood, which can absorb moisture over time. Applying a bit of oil every few months, or during seasonal changes, helps protect the handle and keeps it looking fresh.
  5. Sharpening and Honing
    High carbon steel is easy to sharpen, allowing you to maintain its edge with minimal effort. Regular honing can keep the edge true, and occasional sharpening will restore its sharpness. A sharp blade is safer and performs better, so it’s worth the extra care.

By giving your carbon steel knife a little care and respect, you’re ensuring it will stay a reliable, long-lasting tool and an enduring piece of functional art. With the right maintenance, your knife will be ready for every adventure and task you take on!
