【Description】
This blade is attributed to Tegai Kanekiyo (手掻包清) between the end of the Nanbokucho era and the O-Ei period (1392-1428), according to NBTHK’s appraisal. The swordsmith name Kanekiyo lasted a few generations in Yamato province (today’s Nara prefecture).
The first-gen Kanenaga is known as the founder of Tegai school. Considering the age mentioned in the authentication paper, we believe NBTHK attributed it to a work of the late-gen Kanekiyo based on its characteristics. The school was prosperous during the late Kamakura-mid Muromachi period (1288-1460). It is said that Tegai school belonged to Todaiji temple, and it was located in front of the gate called Tengai Gate (輾磑門). The school name Tegai originally came from the sound of Tengai Gate.
There were five prestigious schools, including Tegai school, during the Kamakura-Nanbokucho period in Yamato province. They are called Yamato Goha(大和五派); Senjyuin(千手院), Shikkake (尻懸), Taima(当麻), Hosho(保昌) and Tegai(手掻) school. They served politically powerful monks and temples in Nara, such as Todaiji temples. They were initially forging swords for military monks who became powerful due to the government’s policy back then.
Monks needed many weapons as there were many political rivalries between influential temples. They required strong weapons like swords to protect themselves. During this time, Tegai school or other Yamato sword schools met the requests from monks. They also forged blades for Samurai during their heyday. It is often the case that those who belonged to Yamato Goha didn’t inscribe their signatures.
Tegai school belonged to YAMATO DEN, which has the longest history among GOKADEN, five traditions of Japanese sword forging techniques. The blades forged by swordsmiths residing in the Yamato region are generally called Yamato Mono.
The swords forged in the Yamato regions are famous for their beautiful Jigane, steel surface, and straight tempering line(Suguha). This blade has a beautiful Jigane with a Suguha tempering line, which shows an outstanding characteristic of the Yamato sword.
This blade 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.

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 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.
Various motifs are designed for this Fuchi Kashira. We think these are family crests and auspicious items. For example, you would find a bird pattern that a bird’s figure with its wings spread. It might be a Tsuru (鶴, crane), and this design exists as a family crest. The Tsuru pattern itself has been treated as an auspicious design that represents longevity.
You would also find other motifs. The Chouji (丁子, precious medicine, fragrance, dye) is a plant that represents happy ma
