Sasuke's sword is special. It's called Kusanagi, although it's not the same Kusanagi that Orochimaru uses.

Also, as explained by Asuma, weapons can be made unnaturally sharp by the elements. In sasuke's case, his channeling of Chidori imbued the sword with apparent unnatural sharpness. After all, last time i checked you couldn't cut rock with a Kunai either.

So no, naruto didn't get stabbed by some random ass sword.
