The Samehada is a unique sword. It is covered in bandages. Samehada is only reliable to one person. That person is Kisame. If somebody else holds it, it will release sharp shark skin type material onto any place and stab them on their hand. There is also another effect. This effect is that it does not cut. It shaves your chakra. Also, it can absorb it at the same time. Also, it can actually move around and return back to Kisame. It was once taken out of Kisame hands. When this happened, it came back to Kisame. Sometimes, it moves around when it shaves your chakra. This sword is a great weapon to have in your artillery.
