Historical Significance:

Sadakuni is regarded as an important smith of the early Shinto period. Some sources suggest he was a peer or even a student of the famed Yasutsugu, while others propose that he was teacher to Kotetsu, another legendary name. His blades are often noted for their excellent forging and resemblance to Yasutsugu’s work, particularly in horimono and hamon execution.

This sword is a rare and particularly well-preserved example of Sadakuni’s craftsmanship, complete with high-quality koshirae and NBTHK Hozon authentication.
