Sesshomaru, Totosai and others in “Unfinished Business”

Sesshomaru

So you absolutely refuse?

Be quiet, you ungrateful mongrel! You know as well as I do, I already made you an excellent sword! The famous sword that you now wear- the Tenseiga. I also forged from a fang given to me by your father. He clearly instructed the eldest brother should have the Tenseiga, and the youngest brother would have the Tetsusaiga! That was your father's last wish. It is a great sword of swords. No greater and no better than the Testsuaiga! You should learn to respect and love it!

Kagome

So that old man also made Sesshomaru's sword?

Miroku

Though, come to think of it, I never seen Sesshomaru unsheathe his sword in any of the battles yet. Have you?

Kagome

No. You're right.
