Aoi Art’s Comment: During the Edo period, the demand for swords decreased, leading to a rise in decorative and visually interesting works, such as those with elaborate hamon, engraved signatures (kiri-tsuke mei), gold inlays, or carvings on the blade.
Samurai would wear a daisho pair when entering and leaving the castle.
In the Shinshinto period, the demand rose again, leading to increased production of tantos.
This piece by Izumi no Kami Minamoto Morimasa is considered to be by the same person as Morikuni.
It is a solid and well-preserved work.
