The smith Kanemichi of Seki in Mino province migrated to Kyoto sometime around the 1570s and 1580s. He was given the name "Daido" ("Great Way"), with a play on the second character of his name alternately read "michi," or "way." Daido was the father of four sons of whom Iga no kami Kinmichi and his successors became influential in the granting of honorific titles to swordsmiths throughout the Edo period.
The squarish gunome of the hamon of this blade is very much in Mino style, and the rather pointed boshi with the long straight return is close to the later boshi of the schools of Daido's sons. The first generation was followed by later smiths who worked much in the same style.
