Fine Grit Rust Eraser
The Naniwa Soko Soko White Rust Eraser is a must-have accessory if you use carbon steel knives or tools. Similar to the Gray Naniwa Rust Eraser but finer in grit, the White Rust Eraser won't scratch as deeply and is suitable for removing light surface rust.
Rub Away Corrosion
The Rust Eraser is a soft and flexible block, 50mm x 40mm x 20mm (2" x 1-1/2" x 3/4") in size. Similar in consistency to a pencil eraser, the alumina abrasive is distributed throughout the entire thickness of the block, so fresh grit is exposed as it wears. The 400 grit fine abrasive quickly removes rust. It can be used dry or with a little water or oil.
