For PC pocket carry and office use, the Kiwi is hard to beat. Nice and pointy for opening mail, can open a box easily if the need arises, sharpens pencils well, peels and slices even large apples nicely, and is benign enough looking that some non knife knuts even call it "cute". They are easy to find and, as TCRooster said, its one of the few knives anyone at the office has ever asked me if they could handle. My other favorite "office knife" is a white micarta baby Horn. These are harder to come by, but super PC looking and as good or better than the Kiwi for all office tasks.
