From Aoi Art : A group of swordsmen called Odawara Sosyu, so they are mixed up with koitame had mokume had mixed with jinie attch and chikei work.
This is a work reminiscent of Muramasa at first glance where the front and back blades are lined up, but the bullion has a background and becomes a stronger bullion.
Yoshisuke is active in Suruga, and powerful bullion has come to be produced in association with Sagami’s Soshuden.
This work is nice excellent jigane that I would like to recommend, although there is a small kitaeware.
These sword makers made swords like footstep of Mt Fuji.
