What is TAMA-HAGANE?
Japanese blacksmithing has over a millennium of history. It dates back to the 1st century A.D. when ancient blacksmiths studied template method from the continent. Copper pottery and rice farming techniques were also introduced to Japan at the same time.
Since then, Japanese blacksmiths had spent centuries to invent the traditional metal forging technique called TATARA(鑪). TATARA is a clay melting pot where you put iron sand and charcoal together to bond these chemicals with intensive heat.
By using this technique, they started to make Japanese swords out of Tatara carbon-steel.
This type of carbon-steel was later called TAMA-HAGANE (玉鋼; Ball-Steel). However, Tama-Hagane, in the early days, still had room for improvement. The schools of Katana (Japanese swords) continued carrying out various ways to make the best steel.
In the Edo period (1603-1868 A.D.), they finally achieved the most steady mass-producing supply of Tama-Hagane. As transport links in the Edo period were far more advanced than those of any previous eras, Tama-Hagane has rapidly spread throughout the country. It was widely used for Shin-TO Japanese swords, since it was deemed the purest form of carbon-steel with the most stable chemical bond. It was also a defining moment in Japanese history when most swordsmiths in Japan used virtually the same ingredient in their blacksmithing.
