Review on Multitool MORAKNIV Companion MG (carbon steel) black/khaki by Agata Buczkowska  (B ᠌

Carbon must be looked after. You can not return from fishing and leave it until the morning - it may darken or rust. You can not cut food (tomato, lemon and the like) without wiping the blade after that, they will cause metal oxidation and the appearance of dark spots on the blade. The solution is the usual cheap polish for cars, for headlights. But you have to rub it long and hard after each use)) Who is too lazy to look after and who does not pursue the appearance of the knife - we put the fat-free and heated knife under hot water into vinegar all night. Overnight, it will take on an even dark shade.
