Jintachi
Jintachi (no) koshirae (陣太刀, jintachi?) is the primary style of mounting used for tachi, Japanese swords, where the sword is suspended edge-down from two hangers attached to the obi. The hilt (tsuka) often had a slightly stronger curvature than the blade, continuing the classic tachi increase in curvature as you go from the tip to the hilt. The hilt was usually secured with two pegs (mekugi), as compared to one peg for shorter blades including uchigatana and katana.
