Tonbokiri

The Tonbokiri (蜻蛉切) is one of three legendary Japanese spears created by the famed swordsmith Sengo Masazane, said to be wielded by the daimyō Honda Tadakatsu, a leading general of Tokugawa Ieyasu.

The spear derives its name from the myth that a dragonfly landed on its blade and was instantly cut in two.

The weapon, along with Nihongō and Otegine, is listed as one of "three great spears" in the Kyōhō Meibutsucho, a listing of famous Koto blades made before the Nanbokucho period and compiled by the Hon'ami family during the Kyōhō era (1716–1735).

[1] The Tonbokiri is owned by a private individual and is on loan to the Sano Art Museum for its collection.
