A sharp blade with a defined tip, integrated fire starter, and diamond sharpener make Bushcraft Survival the ultimate bushcraft knife. The 3.2 mm thick blade in carbon steel has a black DLC coating, which protects it from rust and prevents reflections from the blade. The spine of the blade has been specially ground so that it can be used with the fire starter. Also remember that carbon steel needs a bit of maintenance, so make it a habit to wipe your knife and oil the blade after using it.
