Luke's Blue Saber in ESB?
I was watching Empire Stikes Back again, and I realized that Luke's saber, which was Anakin's, who gave it to Obi-Wan(or maybe he didnt give it to Obi,probably though) was impossible for him to have after A New Hope. Ok, someone correct me if I'm wrong. Kenobi was struct down by Vader in A New Hope, and the saber fell to the ground. Meanwhile, Luke wasn't anywhere near it to retrieve it before he fled on the Falcon. Sooooooo, HOW THE HECK DID HE GET IT?!?!?!? (Unless he built it, but i doubt it since he didnt build his own until Return of the Jedi) I have a feeling this must have beed mentioned somewhere sometime. Anyone have any input? I can't believe I've never noticed
