Immediately following quenching, the blade is tempered, a reheating process that relieves internal stresses and prevents brittleness, ensuring the blade remains tough enough to withstand the pressures of shaving without snapping. This initial forming dictates the blade's balance, weight distribution, and how it will ultimately interact with the contours of the human face during the shaving process.
Manufacturing Shaving Blades Steps
They are precision-inserted into a plastic or metal housing, known as the cartridge head, which features flexible pivots and channels designed to hold the shaving cream or gel. A thin layer of ceramic or chromium is often applied via physical vapor deposition (PVD) to reduce friction and provide a slick, non-stick surface that allows the blade to glide effortlessly.
This is followed by a meticulous honing process, where progressively finer abrasive belts or stones refine the microscopic surface of the bevel. This assembly is then fitted with a final, ultra-fine strop—a soft, abrasive strip (often made of canvas or similar material)—that polishes the blade's edge one last time right before it leaves the factory.
Manufacturing Shaving Blades Steps
Precision CNC machines grind the steel at specific angles, often ranging from 20 to 30 degrees on each side, to create a symmetric and exceptionally sharp apex. Assembly, Quality Control, and the Final Sharpening For cartridge razors, the individual hardened and coated blades are not used alone.
