「日本鍛冶宗匠 伊賀守藤原金道」は、江戸時代初期から幕末まで続いた、全国の刀鍛冶の頂点に立った名門の刀工およびその称号。本作の金道は三代目であり、初代の孫。享保6年（1721年）頃より、「鍛冶惣匠」の「惣」の字を「宗」に改め、「日本鍛冶宗匠」と切れるようになった。本作は日本美術刀剣保存協会の特別保存の証書付き。
また、鍔にも日本美術刀剣保存協会の保存証書がついており、本鍔は桐透鍔で埋忠氏橘宗義の作。埋忠宗義は埋忠家の嫡流で数馬之助と称し、寛文二年（1662年）、延宝九年（1681年）の年紀に活躍した。
“Nihon Kaji Sōshō Iga-no-kami Fujiwara Kanemichi” refers to both a prestigious lineage of swordsmiths—who stood at the pinnacle of the craft nationwide from the early Edo period through the end of the Edo era—and the title held by them. The Kanemichi who created this piece is the third generation, a grandson of the first. Around the sixth year of the Kyōhō era (1721), the character “惣” (sō) in the title “Kaji Sōshō” (Master Swordsmith) was changed to “宗” (sō), and from that point on, the signature was inscribed as “Nihon Kaji Sōshō.” This piece is accompanied by a “Tokubetsu Hozon” (Specially Preserved) certificate issued by the Society for the Preservation of Japanese Art Swords (NBTHK).
The *tsuba* (sword guard) also comes with a “Hozon” (Preserved) certificate from the same society. It is a *kiri-sukashi* (openwork paulownia design) *tsuba* crafted by Umetada Tachibana Muneyoshi. Muneyoshi belonged to the direct line of the Umetada family and was known by the name Kazumanosuke; he was active during the Kanbun (1662) and Enpō (1681) eras.
