After the Ōnin War broke the Ashikaga order, a century of Sengoku warfare armed nearly every province in Japan. The era rewards a discriminating eye: routine work exists in quantity, and beside it stand custom blades of the first rank.
Nagasa 9 sun 5 bu. The first generation Sanjo Yoshinori was a Yamashiro Province swordsmith from around the Oei era (circa 1400) (615 years ago). This tanto exhibits a beautiful sugata with a long dimension typical of its period. The mune is a mitsumune (shin-no-mune). The jigane is itame-hada mixed with mokume-hada with jinie. The hamon is gunome-midare with a deep nioi-guchi, tempered with a spirited yet elegant presence that is truly splendid. The boshi is midare-komi with a tsukiage tip, which is also magnificent. The horimono consists of a Bonji on the omote and a so-no-kenmakiryu on the ura, executed with skillful and masterful carving. It is a truly charming tanto. This tanto is a very precious and old piece by Sanjo Yoshinori, whose extant works are few. It is offered this time at a special discount price.

The Heianjō school (平安城) of swordsmiths represents the principal lineage of Kyōto sword production during the Muromachi period. "Heianjō" is the classical name for Kyōto (Heian-kyō), and the school's smiths — resident in the Sanjō district of the capital — signed variously with the 平安城 (Heianjō) and 三条 (Sanjō) prefixes, a usage that has often caused them to be confused with the far earlier Sanjō school of Munechika. They are an entirely distinct, late group: its two representative masters, Heianjō Nagayoshi (平安城長吉, also read Chōkichi) and Sanjō Yoshinori (三条吉則, of the Fuse 布施 family), are counted as the leading makers of Muromachi-period Kyō-mono (Kyoto-made blades), carrying forward the capital's swordmaking after the Nanbokuchō-period Nobukuni and Hasebe lineages. Both names continued through several generations from the late Nanbokuchō era into the sixteenth century, and the smiths are known to have travelled to forge (desaku) in provinces such as Izumi, Mikawa, and Echizen during the late Muromachi period. The Heianjō style is dominated by a flamboyant hitatsura (full-temper) idiom adopted from Sōshū tradition: a foundation of large gunome-midare mixed with chōji, togariba, and yahazu-ba, with abundant tobiyaki and muneyaki spreading temper across the entire blade surface, nie adhering strongly, and sunagashi and kinsuji coursing through a bright, clear nioiguchi.
The finest examples are so accomplished that they are difficult to distinguish from late Sōshū (Sue-Sōshū) work. A quieter suguha- and ko-notare-based mode close to the Nobukuni tradition is also seen. High-quality horimono — kurikara, bonji, suken, and gomabashi — frequently accompany the blades. The school is not to be confused with the unrelated Heianjō-zōgan (平安城象嵌) inlay tradition of tōsōgu makers. Learn more →

The Muromachi period (1392 to 1573)
After the Ōnin War broke the Ashikaga order, a century of Sengoku warfare armed nearly every province in Japan. The era rewards a discriminating eye: routine work exists in quantity, and beside it stand custom blades of the first rank.
The NTHK’s principal certificate, issued for a blade of considerable quality. It confirms a genuine signature, or, for an unsigned (mumei) work, records the judges’ attribution to a smith or school. The paper carries a detailed worksheet with a numerical point score.
The NTHK (Nihon Tōken Hozon Kai, the Society for the Preservation of the Japanese Sword) is the oldest of Japan’s sword-appraisal bodies, founded in 1910, decades before the NBTHK. After the death of its long-serving head it divided into two successor societies, the NTHK and the NTHK-NPO, both of which continue to hold shinsa. NTHK certificates are known for a detailed worksheet that records a numerical point score alongside the judges’ written opinion, and the society is especially respected for its attribution of unsigned (mumei) work.
