Now, many issues with the idea of using electricity to make a sword heat up and vibrate to cut better.

First up; the only way electricity is gonna help you cut something is by running a plasma torch or a motor. An electrical current passing through metal will not cause it to vibrate, and even if it DID that doesn't actually help with cutting in any way unless it is oscilatting; that is, sliding back and forth. The reason for this is simple. Blades cut on the draw, when they slide across something. Vibrating back and forth? probably gonna make the job harder.

Heat can, theoretically, help you cut through things; that's why the plasma torch example. But it's honestly less cutting and more "flash melting the thing on contact like a hot knife and butter".

I'll also add that you would need to make the sword out of a very particular kind of metal to heat it up with any kind of efficiency; electrical heating generates thermal energy when electricity passes through a metal with a high resistance; the heat is waste energy released because the current has trouble passing through. Most high-resistance metals aren't very good for making swords; and the repeated heating and cooling means it will be undergoing thermal shock and need frequent repair; slowly brittling over time.
