You might not have heard of Mora but they have been putting out a damn good product since 1891. The Bushcraft Survival Black is no exception. A razor sharp blade with its black 3.2 mm thick blade is one of the most sturdy knives Mora has ever made. The carbon steel blade has a black coating which protects against corrosion. You can use the back of the blade with the fire starter.
