Application & Performance Profile
- Precision Slicing: The 1.8mm profile is optimized for horizontal onion slices and paper-thin radish garnishes.
- Left-Handed Geometry: The specific bias prevents the blade from 'steering' toward the right during long slices.
- Edge Retention: High carbon content ensures the 61 HRC edge lasts through multiple shifts without needing a stone.
Critical Maintenance & Carbon Care
- Oxidation Management: This knife is NOT stainless. It must be wiped dry immediately after every use to prevent rust.
- Patina Development: Expect the blade to change color (grey/blue) when cutting acidic foods; this is normal and desired for carbon steel.
- Sharpening Recommendation: Use high-grit Japanese waterstones (2000-6000 grit) to maintain the specific asymmetrical angle.
- Storage: Do not store in a damp environment. A light coating of camellia oil is recommended for long-term storage.
