A lightsaber-blaster hybrid refers to a lightsaber handle that also incorporated a blaster mechanism. In the Imperial Era, Ezra Bridger created such a weapon.
Blasters were generally considered unnecessary by the Jedi Order; however, during the rule of the Galactic Empire, Force-sensitive individuals frequently had to hide their connection to the Force. Openly wielding a lightsaber was not an option. By modifying the hilt, a second emitter could be installed, allowing the weapon to fire energy projectiles akin to blaster bolts. The energy released from this pistol hilt lost coherence quickly, as it wasn't contained within the focusing field that gives a lightsaber blade its shape. These stun bolts, effective only at close range, could still deliver a shock, but their effectiveness paled in comparison to that of a standard blaster or a lightsaber blade.
