I love pocket knives - especially neat ones - like my ZT-0551s and 0561 - and my Tilt!, too. Everything gets carried and used. Opening mail, packages, food, etc. Cutting tomatoes, apples, sandwiches, etc, as well. I admit to stripping coax cable for connectors, too, from time to time. I also test their sharpness by shaving forearm hair. A select few get to be woodcarvers, too.
