Open boxes, cut straps/twine, carve up fruit for a snack, alter the shape of a chopstick (make it pointy, oblong, whatever is needed; chopsticks are another tool), removing those annoying plastic bits that hold tags on clothes, shave those lint bits off clothing, use the spine of the knife to open a bottle, letter opener, open plastic packages (those form-fitted nightmares), pry out staples, stripping and cutting wire, do you fish?, and of course you can use a pocket knife to shotgun a beer (if you're in a frat).

It's weird you never have a use for a knife. Maybe think about ways that using a pocket knife can make life easier for you.
