Chakra Knife

 (チャクラ刀, Chakura Tō) is a special knife utilized by Shintai. The chakra knife is a chakra conducting weapon that is inscribed with a special chakra absorption and transfer seal that allows the user to absorb the chakra of whatever the blade is cutting through the edges of the blade and transfer it to themselves. This not only grants the blade the ability to cut through chakra constructs such as Chakra Threads or even elemental techniques such as the fireball technique but also constantly replenish the lost chakra of its wielder. Much like other chakra conducting weapons, it allows the user to easily flow their chakra and thus increase the sharpness, durability and reach of the blade. Additionally, when it comes in contact with another chakra conducting weapon, it will rapidly drain their chakra and cut through its material at the same time, due to initially enhancing its own properties before transferring it to Shintai.
