Samehada


 * Name:
 * User: Kisame Hoshigaki
 * Debut (Anime): Naruto Episode 81
 * Debut (Manga): Chapter 141

Samehada, a large unique sword of comparable size to Zabuza Momochi's Decapitating Carving Knife. Unlike a regular sword, Samehada is covered in large scales that shave instead of cut, much like a shark's skin (hence the name). It also has the ability to absorb any chakra around it, allowing Kisame to literally cut through his opponent's chakra. The amount that it can absorb is unclear, but it can even consume the demon fox's chakra with no ill effects. Samehada is also a sentient weapon and only allows Kisame to wield it. In the words of Kisame, "It acknowledges only me." When Might Guy attempted to hold Samehada and use it against Kisame, it responded with a flurry of spikes protruding from its handle and found its way back to Kisame. This weapon is also highly sought after by Team Hawk member Suigetsu Hozuki, and is stated to be the sole reason Suigetsu joined Sasuke in his hunt for Itachi Uchiha.

Trivia

 * Only Kisame can wield this weapon, for who ever else touches it, will get stabbed.
 * This may be the source of Kisame's high chakra level.
 * Since it was capable of absorbing the demon fox's chakra with no ill effects, its possible that Kisame just might have one of the largest chakra reserves if its the source of his high chakra level.
