MAC is a unique cutlery maker that bases its manufacturing on ergonomics research. Each knife is made to maximize the comfort of the user. The blade is constructed of high-carbon stain-resistant steel, chromium, as well as molybdenum, vanadium, and tungsten, which give it superior strength and hardness (HRC 60), as well as long lasting sharpness. These knives also feature 45.5° cutting edges, which make them extremely sharp for Western style knives.
