Antique Japanese Sword Katana Signed by Sukesada with
Hozon
Certificate
【Description】
This blade has a signature of Sukesada(祐定). According to NBTHK, this blade was forged in the late Muromachi period(1492-1569 A.D). We contacted
them to confirm this information.
Those who forged swords in the Bizen province(Okayama prefecture) at the end of the Muromachi Period(1492-1569 A.D) are called Matsu Bizen(Matsu means the end). Sukesada school was one of the most famous schools, and it flourished for generations among Osafune sch
ools(The head branch). There were various styles forged by the generations of Sukesada during this period. Approximately 60 swordsmiths used Sukesada as his maker’s name in the Samurai history. In that sense, the swordsmith’s name “Sukesada” worked as a kind of brand that attracted many Samurai.
The swordsmiths in Bizen produced many swords during the Muromachi period as it was in the middle of the Sengoku period(Warring state period). The demand for swords increased among strong feudal lords. It would be nice to have a piece forged in the warring state period when there was so much rivalry between warlords.
BIZEN is located near the Chugoku Mountains, where iron sands, one of the essential materials for making Japanese swords, were abundant. Furthermore, BIZEN swordsmiths had close access to Yoshi River, where they could find water and charcoal. This geological location contributed to the swordsmiths to forge high-quality refined blades. We presume BIZEN was quite active in sword-forging from ancient times. It is said that BIZEN DEN was created by groups of swordsmiths there after the late Heian era(Late 12th century ).
This blade is appraised as a Hozon Token(保存刀剣) issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, well preserved with artistic value.

Cutting Edge Length(Nagasa)
:
61.5 cm( 24.2 inches)
Curvature(Sori)
:
2.1 cm(0.82 inches)
Hamon
:
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
Jimon(Jihada)
:
visible steel surface pattern created by folding and hammering during forging process
Nakago
:
Nakago is the tang of the Japanese sword.
Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tan
g was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.
Koshirae:
Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard).
Fuchi-Kashira
:
A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
Streaky patterns are carved semi-three-dimensionally. Each streak has different width irregularly. A similar pattern is seen at the handle part (please check the Tsuka and Menuki part, which will be mentioned later) also. We guess it was intentionally designed to make the unity. This Fuchi Kashira has a simple design; however, its irregular pattern creates a rhythm and makes this work unique.
Tsuka and Menuki
:
Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The snake is the motif of this Menuki. These snakes twist their slender bodies and form a ring around the middle part. This Menuki has glossy metal color and is in good condition. In Japan, this animal has a deep connection with religion. Many temples and shrines worship the snake as a god. It is said that the snake is also involved in the foundation of the Ryujin Shinkou (竜神信仰, dragon god belief). And it could be said that the snake is one of the special animals that have been familiar to Japanese people since ancient times because of its religious meaning. Some people thought that the water god dwelled in swamps or deep water, and its appearance was a giant snake. Or, a theory says that the souls of the
