This is a masterpiece by Ikkanshi Tadatsuna, renowned as a master carver of the Edo period. The blade features a finely forged ko-itame hada with thick ji-nie and intricate chikei. The hamon is a straight-based notare with abundant nie, strong kinsuji and sunagashi, and a bright nioiguchi. The carvings of a dragon on both sides of the blade are skillfully executed, showcasing the smith's distinctive style in the dragon's eyebrows.
