One of three legendary spears created by renowned gunsmith, Masazane. This spear is said in the hold and used by the Honda Tadakatsu. Spear name comes from the myth that there is a dragonfly landed on the blade and immediately cut in half. So Tonbo (Japanese for "dragonfly") and giri (Japanese for "cutting"), this spear's name translates as "Dragonfly Cutter / Cutting Spear / Saw Dragonflies".
