Medium-Grade Rust-Removal Block — Made in Japan

The medium-grade block gives you a simple way to address surface rust on a suitable knife blade. Start with a small affected area and check the result regularly as you work.

The rectangular shape offers both flat faces and straight edges. Choose the contact area that fits the rust spot, and use light pressure to avoid unnecessary abrasion of nearby steel.

Rinse the knife after treatment to remove loosened rust and abrasive residue. Dry it completely before putting it away, paying attention to areas where moisture can collect.

Keep the block with your maintenance supplies and follow the knife maker’s storage guidance. Regularly drying a knife after washing helps reduce the conditions that allow surface rust to return.
