I think it has been answered before, but Frodo's sword never touched the Witch King. If it had then the Witch King would have died there and then.
There is no fight. Sam does not 'sink his blade into the Ringwraith's thigh', nor does his thrust save Frodo's life. (If he had, the result would have been much the same as in III 117-20:4 the
Wraith would have fallen down and the sword would have been destroyed.)-letter 210
So we can imagine that Frodo's blade would have done the same and the Witch King would have fallen down if his flesh had been pierced. Without even mentioning how Frodo's stabbing arm would have become numb.
