Antique Japanese Samurai Katana from the Muromachi period (1336-1573). Exceptional length of 82 cm. Signed by a famous blacksmith, Yukimitsu, with NBTHK documents, to certify authenticity. The blade is almost straight, which is very rare with katanas, as were the first swords in Japanese history, in the 10th century, called chokutos. These powerful and very sharp sabres were particularly appreciated by the samurai of the Shinsengumi brigade, during the civil war opposing the defenders of the shogunal power to that of the power of the emperor. The sword is in shirasaya, sheath of preservation.
