Of the many great attributes of the Para2, like how it fits the hand, how feathery light it is, lock-up, Spyderco's impeccable F&F ... the list goes on. One thing in particular I love about this knife is how fun it is to open. It's like an automatic but better! You can flick it open with just about any finger you choose, spydie drop it or just smoothly lock it into position. I just love everything about the Para2, I don't know why I waited so long to get one!
