Mcusta Zanmai Beyond Aogami Super – Nakiri Knife 16.5 cm

The Mcusta Zanmai Beyond Nakiri 16.5 cm is a traditional Japanese vegetable knife designed for precision slicing, dicing, and decorative vegetable techniques.

Care Instructions

This knife is crafted from Aogami Super high-carbon steel, known for its superb sharpness and edge retention. However, carbon steel is not stainless and requires proper maintenance:

• Dry immediately after washing – never leave the blade to air-dry.
• Keep in a dry place – avoid storing in damp environments or near water sources.
• Use camellia oil or food-safe oils for long-term storage to protect from rust.
• Avoid contact with acidic foods like onions or citrus for extended periods – they accelerate patina and corrosion.
• Clean using non-abrasive sponges and soft kitchen surface cleaners (e.g. CIF cream) to remove stains.
• Do not put in dishwasher. Heat, chemicals, and moisture will damage both blade and handle.
