Dokuga (毒牙, Literally meaning: Venom Tusk) is a sword created by Tanzō, and wielded by Mizo of Amegakure. The sword itself consists of a dark black blade with an ivory colored grip and is called the "poison sword" (毒刀, Dokutō). The sword is said to be able to poison its foes without any poison being applied to the weapon, which was demonstrated by Mizo using the swords ability to convert his chakra into poison. This poison is fatal enough to cause death within 12 hours of administration and only requires a single scratch to be fatal. This makes the sword a fearsome weapon in short range combat as the poison's effects begin immediately starting with numbness, following with a burning sensation and finally severe nausea.
