Following the cut, the edges are meticulously ground. Using rotating buffing wheels with fine abrasives, the blades are polished to a high sheen, removing microscopic imperfections.

Once verified, the blades are carefully packaged to protect the ultra-fine edge. Heat Treatment and Tempering Heat treatment is the most critical step in transforming soft steel into a resilient, sharp 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. This machine applies immense pressure to reduce the steel's thickness dramatically, transforming the coil into a long, thin strip.

Final Quality Control and Packaging The finished blades undergo a stringent inspection process to ensure they meet exacting standards. The shaped blades are heated to a specific temperature in a controlled furnace, then rapidly cooled, or quenched, in oil or water.
