Special feature : It is said that the founder of Bungo Takada school was Tomomitsu or Tomoyuki.
Takada Swordsmiths in Shinto age engrave the last name “Fujiwara”, and so they are called also Fujiwara Takada.
The neighbor of the Takada school was Hizen school.
Hizen sword makers were controlled by Nabeshima daimyo and imported western steel from Holland which is called Nanbantetsu.
I think Hizen sword makers used this steal and mixed up with Japanese Tamahagane.
So Hizen jigane was very big different from Takada school.
Takada school tried to make cut well sword.
Early stage from late Muromachi to Kanbun era, Takada school swords were high reputation for cut well sword and good jigane.
This blade is nice jigane and good hamon.
The blade shape is very wide and massive.
