To date it has been my swiss army knife or victorinox multitool, for opening packages, and random tool use around the house (a quick tightening of a screw, opening a bottle etc).
However, now that I have discovered this forum, I have picked up a couple of nice edc folders. So I have been rotating through those at the bedside or desk drawer, and they now handle the occasional cutting tasks that come up. Somewhat perversely, I have taken to slicing food with my kershaw random leek, when I happen to have it on me in the kitchen.
