swordsmithing

Swordsmithing is the craft of making blades, from initial concept to finished weapon or tool. It encompasses design, material selection, forging, heat treatment, and finishing. Traditionally done by a single smith or a team, often with apprenticeship and tools such as an anvil, forge, hammers, tongs, grindstones, and quench tanks. The aim is to create a blade with a balance of hardness for edge retention and toughness to resist shattering.

Swordsmithing has deep regional variation. In East Asia, Japanese nihonto reflect tamahagane steel and differential tempering to create a hard edge and tougher body. In Europe and the Middle East, crucible steels, pattern welding, and folded constructions produced durable blades. In modern times, techniques have evolved with industrial steelmaking and precision heat treatment, while traditional methods are preserved by artisans.

Techniques and materials include high-carbon steels such as 1060-1095, through to alloyed steels like 5160, are common. Forging shapes the blade, often by hammering heated stock on an anvil and sometimes by forge welding or pattern welding. Heat treatment includes normalization, hardening via quenching in oil or water, and tempering to adjust hardness and resilience. Finishing involves bevel grinding, polishing, etching, and sometimes differential tempering to create visible hamon or pattern.

Modern practice and considerations: Swordsmithing can be a historical craft, a hobby, or a professional trade. Reproductions and functional blades are made for collectors, martial artists, and reenactors; many regions regulate weapons and export. The field emphasizes safety, craftsmanship, and preservation of traditional methods alongside innovative blade engineering.
