The carbon steel blade has a black DLC coating that protects against rust to a certain extent and also prevents reflections from the blade. However, remember that carbon steel requires maintenance. So make it a habit to wipe down your knife after use and oil the blade. The spine of the blade has been sharpened so you can use it with a fire starter - meaning a critical fire is never far away. The Scandi grind makes the knife easier to keep sharp, and the back of the blade has been ground so that it can be used with a fire starter or flint.
