Dropped Lightsaber YKTTW Discussion
The character loses his or her weapon at a bad time. Chances of recovery usually favor heroes.
The main example that comes to mind is in Star Wars: TPM where both Qui-Gon's and Obi-Wan's sabers gets knocked away...during the Darth Maul fight. Qui-Gon, in the only example of the trope that I can think of favoring a villian, gets killed. Obi, however, Forces his saber back to him and kills Maul.
