Features:
Rai Kuniyasu was a swordsmith who moved from the Rai school to Echizen.
He combined the stylistic elements of the Rai tradition with the characteristics of Echizen smiths.
Although some references date his work to the late Kamakura period, it is believed this sword was actually forged in the late Nanbokucho to early Oei period.
His works are generally bright in appearance, with visible hada and often show utsuri.
