*Potencial Spoiler* swali about Tenseiga. DON'T answer if wewe have not watched Inuyasha, The Final Act.

Ok so the Tenseiga was originally a part of Tetsusaiga that was carved off and formed into a separate blade, because Inuyasha's and Sesshomaru’s father didn't want that power inherit in the sword when Inuyasha attained it. Depending entirely on Sesshomaru to master the technique so it could be made safer for Inuyasha to use it once reabsorbed back into the original sword... ok, well my swali is this: when the Medoe Zangetsuha was reabsorbed why didn’t the Tenseiga die?

And why is it still able to connect with the netherworld in the way of being the Healing blade and the blade that cannot cut? After observing the story line zaidi closely I came to the conclusion that the swords ability to cut down beings of the other world was directly connected to the power of Shinshiki the demon from which the Medoe technique (or in other words the ability to tap into the other side) originally came, for how else could the sword, au the Inu no Taiso have attained the ability to create a sword like the Tenseiga?

This is just a curious issue, and since the origin of the swords healing ability was never covered other then saying it was a sword created kwa The Great Dog Demon through Totosai that unfortunately there is likely no definite answer to this question, which is fine, but I still would like some majibu if there are any to give. So in short what’s your theory, why didn’t Tenseiga die when the Medoe was absorbed back into Tetsusaiga?
