Kaneshin - Crean Mate, Rust Eraser 6.5 x4.0 x 1.8cm

Crean Mate or Clean Mate (depending on where you are from) is the perfect tool to remove rust from knives or anything else for that matter. Ideally add a little camellia oil (water ok too) before scrubbing away to remove rust or other stubborn marks or stains.
