A patina is a natural protective layer on carbon steels that protects the blade from further oxidation and gives it a look of rough finish. It is produced by the oxidation of steel surface and this process is even quicker if a knife comes into contact with various acids. You can recognize a patina by its characteristic colours: first you see golden yellow that changes to deep blue, which then transforms to purple and, in the end, to grey that darkens over time. If you notice red dots of rust, you should remove them. • --------------------------------------------------------------- • LET'S CONNECT! • ➜ Subscribe Here! - https://www.youtube.com/sharpedgeshop... • ➜ Instagram - / sharpedgeshop • ➜ Facebook - / sharpedgeshop • ➜ Website - https://sharpedgeshop.com/ • ➜ Be sure to sign up for our weekly newsletter - http://eepurl.com/dbdiiX
