NAME OF ITEM Tessaiga
ORIGIN OF ITEM The Tessaiga is made from the fang of Inuyasha and Sesshomaru's father. After it is broken in a fight with Goshinki, it is repaired using one of Inuyasha's fangs.
DESCRIPTION Initially it resembles a rusty, chipped katana, but when used to protect his human companions, the sword transforms into a giant blade.
WHAT DOES IT DO? As the series progresses, Inuyasha learns many new techniques with the sword, such as the Kaze no Kizu (Wind Scar), Bakuryuha (Backlash Wave), Kongosoha (Adamant Barrage) and Meido Zangetsuha. The sword also has the ability to slice through powerful barriers.
IMPLICATIONS This sword is Inuyasha's most powerful weapon, and allows him to go toe-to-toe with demons who are physically much more powerful than he is. Initially Inuyasha's half-brother Sesshomaru jealously covets the sword, but eventually realizes that the sword was made specifically for Inuyasha.
