Carbon steel knives are reactive by nature - they patina with use, which is desirable, but left wet or in contact with acidic foods they can develop rust spots. The Naniwa Rust Eraser handles minor rust removal quickly and effectively without damaging the blade. It works like an eraser - wet the surface, rub the rust eraser over the affected area, and the abrasive block lifts surface rust without aggressive scratching. Works equally well on kitchen knives, carbon steel pans, stainless sinks, and other metal surfaces that have developed light oxidation or rust spots.
The medium grit gives enough abrasive action to remove real rust while being gentle enough for knife blades. Use with caution on polished or mirror-finish blades as it will leave light surface marks - it is best suited for kurouchi, nashiji, kasumi, or matte-finish knives where minor surface marks are less visible. At 50mm x 40mm x 20mm it fits comfortably in hand for controlled application. A practical and inexpensive addition to any carbon steel knife care kit.
Care Instructions: Rinse and dry after use. Store dry. Replace when the block becomes too small for comfortable use.
