[Suzerain of Sheol]

Oh, I forgot to mention, if you look at my katana rack, the bottom one (the really long one) is actually two short koadchis in one sheath, the end of the scabbard is the hilt of the second one.

The one above it is reverse-bladed, and the one above that also has two swords in one sheath, though it's more of a katana/wakizashi combo. If you look close, the top part of the sheath is wrapped like a sword-hilt, that's the hilt of the wakizashi. They're sheathed parallel to each other.
