Case hardening is a process of increasing the carbon content at the surface of very low carbon

steel. It is done by placing the object to be hardened in a sealed container along with carbon-

containing material; in antiquity, this material was usually horn or hide. The container would

then be heated until it was glowing red, and held at that temperature for a while, based on the

size of the part being hardened, allowing carbon to penetrate the steel by a few thousandths of

a centimeter. At that point, the object would be dumped out of the container into a water bath

to quench it, resulting in a very hard surface, but completely unhardened core. There is very

little evidence of this having ever been done to swords except, perhaps, the very earliest of

iron blades. Due to the inherent weakness of a sword's cutting edge, coupled with the high-

impact stresses of combat, such a thin hardened surface over a soft core would provide very

little advantage in terms of edge-holding, other than mild wear resistance.
