Obi-Wan: "I have something here for you. Your father wanted you to have this when you were old enough, but your uncle wouldn't allow it. He feared you might follow old Obi-Wan on some damned-fool idealistic crusade like your father did."
Luke: "What is it?"
Obi-Wan: "Your father's lightsaber. This is the weapon of a Jedi Knight. Not as clumsy or random as a blaster. An elegant weapon for a more civilized age."
