"Assault with a deadly weapon" covers just about anything.
Edit:
I think that Faye actually forged that sword. Additionally, given that we've seen Dora drive it into the surface of the counter without much effort, I suspect that it is fully combat-sharpness.
All that shows is that it was sharp at one time. If it's made of stainless steel, it won't have
stayed sharp for very long, as anyone who's ever had a stainless steel pocketknife (Boy Scout knife, Swiss Army knife, etc.) can verify. And if it's carbon steel, which is more likely if Faye made it herself, then it'll hold an edge longer but need a lot more rust-prevention care than it's probably gotten while lying around on a shelf under the counter.
Still, a rusty but sharp sword will probably do more damage than an unrusted but dull blade, assuming it hasn't rusted all the way through. Plus, anyone it hits will need to get a tetanus booster shot, too!
