What is Mino-den in Japanese Katana terminology
"Mino-den" is one of the "Gokaden", a traditional method of sword making that developed in what is now Gifu Prefecture, following the middle of the Kamakura period. It is characterized by a blade pattern that mixes "Gonome" and "Togariba". Due to its excellent sharpness and operability, it was well known among warlords during the Warring States period. In the Edo period, Mino blacksmiths (Seki blacksmiths) migrated to castle towns of various feudal lords, including Edo, Osaka, and Kyoto, and spread nationwide.
