Companion Heavy Duty is a powerful tool for bushcrafters, hunters and outdoor people. If you need a knife that has great strength requirements, we recommend the Companion Heavy Duty with its three-layer injection molding and the slightly blunter edge angle of 27° for maximum sharpness retention (default is otherwise an angle of 23°). The knife has an extra-large ergonomic handle with a soft, high-friction grip. The knife has a blade of 0.125" (3.2 mm) steel with high-load capacity. Scandi Grind. Plastic sheath with a belt clip. If you need to hammer on a knife, it needs to be very strong. We have thought this through with a three-layer thick polymer molding, and an extra thick blade, which literally stands up against any beating you give it."
