As a swordsman, I can tell you that if you're entering combat with a sharp blade, you are not preparing to knock your opponent out.

In less pedantic terms, though, having a nonlethal direct combat option goes against the spirit of the game. Nonlethal corvo goes out of his way to NOT engage targets.
