The Masamune is designed as a Japanese odachi blade. The design and color of the tsuba (guard) and tsuka (hilt) have varied alternating between blue and gold and entirely black. The blade's exact length varies; usually measuring at least as long as Sephiroth is tall or slightly longer, which would make it approximately six-to-eight feet long. The angle of the curve of the blade also varies, but it is never entirely straight.
