Antique Japanese Sword Katana signed by Korekazu with Hozon Certificate 【Description】 Summary This blade was signed by Musashi Daijo Korekazu (武蔵大掾是一). Based on the signature, we believe it was signed by the first-gen Korekazu, active during the early Edo period (1648-1673). The maker’s name Korekazu lasted seven generations. He belonged to the Edo Ishido school, which flourished during the Edo period. He played an essential role in spreading the fame of Edo Ishido school (江戸石堂派) nationwide. The first-gen Korekazu was originally from Omi (近江, Today’s Shiga prefecture). It is said that he was a descendant of Ichimonji Sukemune(一文字助宗) from Bizen(Today’s Okayama prefecture). He moved to Edo and founded the Edo Ishido school at the beginning of the Edo period. This school became one of the most popular ones in Edo city, Musashi Koku. And the third-gen Ishido Korekazu became an Okakaekaji for the Edo government in 1721, exclusively forging swords for the Tokugawa clan. The Foundation of Ishido School Ishido school was founded by Sukenaga, an offspring of Ichimonji Sukemune, who made Fukuoka Ichimonji school in Bizen province (Today’s Okayama prefecture). During 1492-1501 (Late Muromachi period), Sukenaga and his school moved from Bizen province to Omi province after being summoned by Gamou family, a powerful feudal line in that region. Sukenaga started to live in front of Ishido temple, and he changed his surname to Ishido. As of the early Edo period, many Ishido swordsmiths moved to other parts of Japan, looking for better opportunities. Following this trend, Ishido Korekazu moved from Omi province to Edo city (Today’s Tokyo). There are four areas: Edo, Osaka, Kishu(Wakayama prefecture), and Chikuzen(Fukuoka prefecture). It is appraised as a Tokubetsu Hozon Token (特別保存刀剣) 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, especially well preserved and high quality with artistic value. *Please keep in mind that there are a couple of Kitae Kizu on the blade. If you like to know the detailed condition, please feel free to contact us. 【Blade】 Cutting Edge Length(Nagasa) : 68.7 cm ( 27.04 inches) Curvature(Sori) : 1.8 cm (0.70 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 Kissaki : Kissaki is the tip of the Japanese sword. 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 tang 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. This fuchi-kashira depicts traditional farming tools such as a sickle (鎌, kama) and a carrying basket(背負い籠、Seoi Kago). The basket, commonly used in agricultural work, was typically made of bamboo. Bamboo was highly valued not only for its light weight and strength but also for its flexibility, which made it an easy and practical material to use. Tsuka and Menuki : Tsuka is the handle of the Japanese sword and Menuki is its decoration. The theme of this Menuki is a tiger (虎, tiger). The tiger is a brave animal. A theory says people considered the tiger pattern would protect people from evil spirits. Therefore, its pattern has been treated as a talisman. The tiger design has also been regarded as the symbol of life activity when “tiger” is written by a Japanese Kanji character (漢字, a kind of Japanese letter) based on its meaning. It is said people wished boys’ healthy growth
