Samehada is a massive, sentient sword with a unique, organic appearance resembling a combination of a shark and a sword. Its blade is covered in rough, scale-like textures that can absorb chakra, with a jagged, toothy edge that gives it a fearsome look. The handle is wrapped in bandages for grip, and the overall design features a muted color palette with shades of gray and blue, emphasizing its aquatic and predatory nature.
