Scratched stainless steel repairs its own shield
Stainless steel does not resist rust because it is coated, but because of chemistry. The chromium it contains, at least about 10.5 percent, reacts with oxygen to form an invisible oxide film on the surface, and if that film is scratched it re-forms quickly wherever air reaches the bare metal. On this all-steel hooked blade knife, blade and handle both benefit, which is why a quick rinse and a dry cloth keep the whole 34 g tool in order.
