This is an aerial I've been learning this past week where you let the balisong rotate one and a half times, catch the side facing away from you, and pull it into a thumb rollover. This aerial was first done on video by legendary flipper Murnax in 2005. I do the aerial once at the beginning and once at the end.
This is what happens if the knife falls on your ankle, and also why when working with the balisong you should wear long pants:
That's the second bad cut I've gotten on an ankle.
