Tetsusaiga and Tenseiga

This is one of my fave epis. Anywyas here we meet Toutou-sai the swordsmith who forged the Tetsusaiga. It seems Myouga told him Inuyasha has mastered the blade but Toutou-sai has his doubts. Meanwhile Sesshomaru has Jaken out looking for Toutou-sai as he wants a new blade. Toutou-sai is nowhere to be found. Sesshy is not very pleased by this. Anywyas Sesshy eventually meets up wiuth everyone & demands a new blade. It seems Sesshy was the one who was after Toutou-sai in the first place. He & Inu fight & when it seems like Sesshy has won he once again demands a new blade only to be told his blade the Tensaiga is just as good if not better than the Tetsuasiga which shocks everyone since no one has ever seen Sesshy use it. Sesshy says it's useless & Toutou-sai makes a diversion & escapes.Anywyas we see that the blade he carries can't kill after he slashes Jaken with it & Jaken is surprised to still be alive afterwards. (Sesshy actually flashes his pearly whites here!) Later on that night Toutou-sai explains to the gang about the blades. Meanwhile Sesshy has anew dragon's arm & the next day he uses it in a battle with Inuyasha. During the battle he tells Inu he'll never master the sword because he can't see the Wind scar....
