If you need to hammer on the knife it needs to be very strong. Morakniv has thought this through with a three-layer thick cast molding, and an extra thick blade, which literally, stands up against the hammer. If you choose the fluorescent orange color, you can find the knife quickly when you need it. The military green model is more discrete and blends in with surroundings. The Companion Heavy Duty is the optimal companion for rigorous adventures and challenges. The robust handle and somewhat blunter 27° angle edge give it maximum edge resiliency. The blade is extra thick (3.2 mm) to be able to withstand all kinds of pressure and it’s made from Swedish carbon steel, which is simple to sharpen. Remember that carbon steel needs maintaining though, so make it a habit of wiping the knife and oiling the blade after usage.

Knife blades of high carbon steel can be hardened to HRC 59-60 giving best possible sharpness to lowest price ratio. Knives made from above mentioned steel grades will after some use achieve a dullish grey finish. However, this will not negatively affect the quality of the blade. On the contrary it will somewhat improve the resistance to corrosion.
