Tamahagane (玉鋼) is a type of steel made in the Japanese tradition. The word tama means 'precious', and the word hagane means 'steel'. [ 1 ] Tamahagane is used to make Japanese swords , daggers , knives , and other kinds of tools.
The steel used in sword production is known as tamahagane (玉鋼:たまはがね), or "jewel steel" (tama – ball or jewel, hagane – steel). Tamahagane is produced from iron sand, a source of iron ore, and mainly used to make samurai swords, such as the katana, and some tools.
Tamahagane (玉鋼) is a general term for steel, not used prior to the Meiji Era, literally meaning "precious steel". Steel is smelted at Shimane facility for Japanese swords ( nihontō ( 日本刀 ) , commonly known as katana ( 刀 ) ) by contemporary Japanese forge masters like Kihara Akira and Gassan Sadatoshi is still smelted in a tatara .
The legitimate Japanese sword is made from Japanese steel "Tamahagane". [132] The most common lamination method the Japanese sword blade is formed from is a combination of two different steels: a harder outer jacket of steel wrapped around a softer inner core of steel. [133]
Tamahagane. Japanese smiths discovered, similarly to many others, that iron sand (with little to no sulfur and phosphorus) heated together with coal (carbon) made the steel they called tamahagane. This allows the sword to have the strength and the ability to hold a sharp edge, as well as to cause the sword to tend to bend rather than flex under ...
Katana are traditionally made from a specialized Japanese steel called tamahagane, [60] which is created from a traditional smelting process that results in several, layered steels with different carbon concentrations. [61] This process helps remove impurities and even out the carbon content of the steel.
The high carbon tamahagane and higher carbon steel, called nabe-gane, will then be forged in alternating layers, using very intricate methods to form the kawagane, (or, “skin steel”). The most useful process is the folding, where the metals are forge welded, folded, and welded again, as many as 16 times.
