Besides, weapons like Kusanagi were forged, it's not impossible that Sasuke learned how to make his own, or an imitation thereof.

And lastly, Sasuke's sword effortlessly pierces stone, so i don't think it's a generic sword by any measure. It aint forged, its a sacred weapon. Its like saying the sealing pot can be forged. Enma was dying to take it back with him, that means no one can recreate the original one. And btw sasuke's kusanagi cant extend and even then it phased through steel which means kusanagi can even become intangible.
