Hige—kiri (Beard cutter) and Hiza—maru (the Hobbler) are a legendary pair of long and short blades said to have been owned by the Genji clan. The smith is unknown, but they are believed to have been forged at Minamoto—no—Mitsunaka's order in the Heian Era. The larger blade got its name for being so exquisitely honed it can separate an enemy from his beard before taking off his head; the smaller, for its ability to sever legs with a single well—placed strike. Hiza—maru is said to have been used by Minamoto—no—Yorimitsu on his mission to slay the Shuten Doji demon in the hills outside of Kyoto, where he used it against a giant spider called the Tsuchi—gumo. In later centuries these swords were kept as family treasures by powerful warlords such as the Kai—Takeda clan, but their true provenance is difficult to ascertain.
