One of the great advantages of energy blades is that, since the tech for it doesn’t really exist yet, no one can say exactly what shape or size they should be. I haven’t yet seen the obvious plot twists that would come from energy blades altering their shapes by biometrics to ‘twist’ or ‘barb’ inside an enemy and wink out on contact with an ally. Physiognomy can change tactics just as much as technology, after all . . . I’d be tempted not to size them down, but give them a more aggressive angle or shape.
