✓ Therefore, the technology combines the best out of both types of steel. The composition of the blade is not the only factor, defining its well-known and well-recognized properties, though. The method by which it’s produced is just as important to the creation of a San Mai steel blade. To create San Mai blades, metalsmiths follow a specific thorough process that starts with picking out steel for the center and the outer layers.
✓ This choice is based on their carbon content — the more carbon in the steel, the “harder” it is. Once the proper combination of steel is found, the harder metal is sandwiched between two plates of the milder metal, then they are forged to bond them together. Sharpening the blade has to barely expose the central, harder core to create the sheer edge, whereas the milder metal will create a defensive coat around it.
✓ Such manufacturing technology is an advantage in itself, as it provides an outstanding cutting edge together with a corrosion-resistant exterior. This combination of different elements and their interplay is what gives a San Mai blade its unique and legendary reputation.
