An Energy Knife acts as a mini lightsaber, at least from what the description and icon looks like. Basically a laser cutter on the edge to give better cutting potential, but for some reason it doesn't affect Cut-Throat, which it should. After all, you are going for the throat region and having a lightsaber cut through it compared to normal steel is far more effective.
I would add to this that all Serrated Knifes should also give better bleed damage but shorter duration, while Daggers could give additional bleed duration, but worse bleed damage. Combat Knifes on the other hand could give a flat -1 decrease in CD, or a decrease in AP cost by 5.
The Hook is also a nice addition to buffing Cut-Throat, only wish there were more similar buffs to basic weapons. For example if the target is incapacitated then you can use Cut-Throat from any direction.
