Balisongs are really useful and utilitarian tools when used as such. They have a side benefit of being fun fidget objects too, I was sitting here doing my swing open and closed just repeating it. It looks cool going fast but it is just the same motion over and over and definitely not approaching anything close to what is in the video. I can make my opening and closing motion "look cool" by waving my arm around to most people, but that lady would laugh at me in the video.
Of note in my steps: My sample's latch gets stuck on the G10 (someone else had noted this on their sample) and wont unlatch if the blade edge is facing out from my palm. If yours does unlatch with the edge out from palm reliably, then the first 2 pics and the step of rotating to put the safe handle in my fingers is not needed technically.
You can squeeze to unlatch and already be in position like picture 3 in my other post.
