By Sarah Leeson • Dec 19, 2017 Sarah Leeson / Michigan Radio Listen Listening... / 5:23 Stateside's Sarah Leeson went to a Terra Prime Light Armory workshop in Ann Arbor to see some lightsaber sparring. Star Wars: The Last Jedi opened with the bang of a thermal detonator this weekend, becoming the second-highest grossing opening weekend for a film ever in North America. But your local theater isn't the only place where aspiring Jedi knights can be found learning to wield a lightsaber. Chad Eisner co-founded a group called Terra Prime Light Armory in 2012. The group promotes traditional martial arts and weapon arts by sparring with lightsabers.
