From Thor’s mighty hammer Mjölnir, to Bruce Lee’s trademark nunchucks, to the curved blades of the Klingon bat’leth, pop culture has a wide range of weapons in its armory. In this episode of Expert Witness, we sit down with fight coordinator and historical fencing master Jared Kirby (again) to go over the pros and cons of some iconic Hollywood weaponry. In Vulture’s video series, Expert Witness, we ask scientists, historians, and other professionals to give movies and TV-shows a good old-fashioned fact-check.
