Japanese swordsmithingJapanese swordsmithing is the labour-intensive bladesmithing process developed in Japan beginning in the sixth century for forging traditionally made bladed weapons (nihonto) including katana, wakizashi, tantō, yari, naginata, nagamaki, tachi, nodachi, ōdachi, kodachi, and ya (arrow). Japanese sword blades were often forged with different profiles, different blade thicknesses, and varying amounts of grind. Wakizashi and tantō were not simply scaled-down katana but were often forged without a ridge (hira-zukuri) or other such forms which were very rare on katana.
Toyotomi HideyoshiToyotomi Hideyoshi, otherwise known as Kinoshita Tōkichirō and Hashiba Hideyoshi, was a Japanese samurai and daimyō (feudal lord) of the late Sengoku period regarded as the second "Great Unifier" of Japan. Hideyoshi rose from a peasant background as a retainer of the prominent lord Oda Nobunaga to become one of the most powerful men in Japan. Hideyoshi succeeded Nobunaga after the Honnō-ji Incident in 1582 and continued Nobunaga's campaign to unite Japan that led to the closing of the Sengoku period.
