Following the cut, the edges are meticulously ground. Manufacturers typically use a specific grade of stainless steel, chosen for its corrosion resistance and ability to maintain a sharp edge.
The Making of a Razor Blade: From Steel Coil to Precision Edge
Before processing, this steel arrives in large coil forms, which are then cleaned and uncoiled to prepare the material for the initial rolling process that will determine the blade's fundamental thickness and strength. Many premium manufacturers then apply a thin coating, such as PTFE (polytetrafluoroethylene) or other polymers.
This coating reduces friction against the skin or hair, allowing for a smoother shave and helping to protect the sharp edge from oxidation. Final Quality Control and Packaging The finished blades undergo a stringent inspection process to ensure they meet exacting standards.
The Detailed Process of How Razor Blades Are Made
Precision is critical at this stage; the thickness must be consistent along the entire length to ensure a uniform cutting edge. To improve corrosion resistance and create a smoother glide, they undergo a polishing process.
