In "Inuyasha", which knife is the most powerful, broken teeth, teeth from the clouds and fighting ghosts and gods?

Broken tooth-Sesshomaru's own knife. Sesshomaru started this knife in his heart all the time in the Quling World War I, and his left arm was cut off by Inuyasha. It symbolizes another upgrade of Sesshomaru, which is more powerful. I personally think that broken teeth will play an important role in the fate of Sesshomaru. Of course, it has a positive effect-because it brought many benefits to Sesshomaru as soon as it appeared, and its role in the future is irreplaceable. The moves are unknown, and it is estimated that the black dragon break and the black dragon break in Upanishads, because Sesshomaru can use these two moves whether it is playing ghosts or natural teeth. However, one thing is certain, that is, what is cut from a broken tooth can never be repaired, and the pieces of meat cut from a broken tooth (especially from Naraku) will lose their regeneration ability.

Of course, broken teeth are terrible. Now only Sesshomaru's broken tooth can kill Naraku, and Naraku hijacked the bell for fear of Sesshomaru and broken tooth.
