Care advisement: This blade is fully carbon and care must be taken to avoid rust. Wipe dry after each use and ideally between preparing different products, especially when using acidic and salty products. A patina will form over time helping increase stain resistance slightly. Hand wash and dry only. Store away from liquids and open windows. Keep the blade covered when storing or traveling. Use only on appropriate cutting surfaces such as soft woods and plastics.
