The Naniwa Rust Eraser is a must-have accessory if you use high carbon steel knives or tools.
The Alumina abrasive is distributed throughout the entire thickness of the block, so fresh grit is exposed as it wears.
The fine grit abrades quickly through rust. It can be used dry or with water. You’ll get a higher polish by wetting the knife first and even more polish by using a drop of oil on the blade.
This is a very high quality fine eraser and will give you much use and satisfaction.
