Well you're missing out on some fidget flicking fun while watching tv or sitting at your desk at work. (Or anywhere else...) Who needs a spinner when you have a Spyderco in your pocket?
Or driving... two knives at a time
Out of all my Spydercos, the only one I can't flick is Native 5 LW. Not without giving it some wrist action. Otherwise, thumb, middle finger, upside-down ring finger, all flickable.
