Samehada is a large sword, roughly as tall as a full-grown man and comparable in size to the Kubikiribōchō. Though usually wrapped in bandages, Samehada's construction is atypical in that its actual blade is comprised from a series of downward-facing scales running along the entirety of its length until its hilt, at the base of which is a small skull. Samehada grows larger in proportion to the amount of chakra it absorbs, causing its scales to become so long that they ultimately resemble shark fins and its mouth, located at the tip of the blade, to become even more pronounced with visible teeth. Keeping Samehada wrapped in bandages apparently helps to inhibit this growth to a certain extent.
