Daisho with Koto Blades (fss-819)

Item description:

These swords are mounted in an elegant daisho Koshirae. The saya are elaborately finished in a uniques style of Samegawa. The Same/ray skin is attached to the wooden core and ground down flat and polished after lacquer is applied.  This finish is not usually found in this condition.  An interesting note: The kurikata of both saya are finished in same(rayskin) which is a rarity. The Motif is of Dragons throughout finished in gold waves and clouds as a backdrop.  All the fitting are original and matching.  This is a true original Daisho.  The koshirae has an ito of blue that is also very old and the sageo are black in color. The Kodzuka blade and ko-gatana are in a dragon motif also with a shakudo/nanako finish. The ko-gatana blade is signed. The menuki are also well made in a dragon motif that compleat the koshirai. The tsubas are of a Buddhist symbol repeated throughout finished in iron. These tsuba are spectacular and the amount of work that went into them is incredible.  Both swords have matching gold washed habaki and seppa. Please note that for koshirai or mounts to receive papers they must be original and not put together.  This is a real daisho set.

The katana is signed Kanesada . A beautiful blade in pristine polish and loaded with activity from the Shinto period. Within the gunome-midare hamon there is hotsure, sunagashi and kinsugi. The hada is a dense and beautiful itame and mokume mix with some masame and loaded with ji-nie. It has the appearance of the evening sky!

The wakazashi was attributed to kaneharu of the shinto period. A mumei piece this sword has a hamon with O-gunome-midare throughout. The hada is an itame and mokume with ji-nie. This sword reminds one of the work of the Kanemoto line.

Both swords date back to the 1500’s and are koto blades.

Information on daisho history:
The wearing of daishō was limited to the samurai class, and became a symbol or badge of their rank. Daishō may have became popular around the end of the Muromachi period (1336 to 1573)as several early examples date from the late sixteenth century.An edict in 1629 defining the duties of a samurai required the wearing of a daishō when on official duty. During the Meiji period an edict was passed in 1871 abolishing the requirement of the wearing of daishō by samurai, and in 1876 the wearing of swords in public by most of Japan’s population was banned; this ended the use of the daishō as the symbol of the samurai, and the samurai class was abolished soon after the sword ban.
