I never use my EDC knives for cutting cardboard boxes, carving wood, or hunting. This is like using a Rolex to snuff out a cigar. A sharp folding knife should only be used as a self-defense weapon. After its first use, the police will probably seize it for evidence. Just like a handgun you fire to protect your family. Even diving knives are reserved for self-defense, not shucking oysters. While traveling in a car, it might make sense to carry one (EDC) knife on your person, and another in your toolbox.
There are other tools like boxcutters, hacksaws, chisels, butcher knives, and pruners for most cutting jobs. A two sided diamond sharpener does a fairly good job of sharpening and finessing the blade. Strops are for barbers who still shave people the old-fashioned way, and like a polished blade. Some people are just perfectionists.
