Immediately after quenching, the blades undergo tempering, where they are reheated to a lower temperature and then cooled slowly. This machine applies immense pressure to reduce the steel's thickness dramatically, transforming the coil into a long, thin strip.
Precision Grinding Razor Blade Edges: The Key to Ultimate Sharpness
Core Material Selection and Preparation The foundation of every high-quality razor blade is the steel alloy itself. Understanding how razor blades are made reveals a complex process involving metallurgy, precision tooling, and rigorous quality control to achieve the sharpness and durability consumers expect.
Many premium manufacturers then apply a thin coating, such as PTFE (polytetrafluoroethylene) or other polymers. This relieves internal stress, preventing brittleness while maintaining the hardness required for a durable, sharp edge that can withstand repeated use.

Using rotating buffing wheels with fine abrasives, the blades are polished to a high sheen, removing microscopic imperfections. Initial Rolling and Strip Formation The cleaned steel coil is fed into a series of heavy-duty rolling mills.
