One thing is for certain, if you start carrying a pocketknife, you will use it, and you will come to rely on it, and after carrying it around for a while, you will feel ill prepared, ill at ease, and downright naked when you don't have it with you.
You'll be surprised how often you use it. I guarantee you do a lot of things right now with your fingers or possibly your car keys that are much more easily and neatly done with a knife. A knife is a letter and package opener, fingernail cleaner, staple remover, pencil sharpener, knot untier and lottery ticket scratcher. If you carry pocketknife you'll never have to go looking for a scissors ever again. If you are bored or idle or have to wait around for something any stick you pick up off the ground becomes a source of diversion. You will discover whittling, and you will learn to sharpen a knife, which are both very practical skills.
And if you decide to carry a Swiss Army Knife or a multitool, this principle is compounded, because then you basically have a mini toolbox in your pocket.
There's no disputing that one knife is not too many. I, like most people on this board I'm sure, probably have too many, or at least more than I'll ever need. However, you need at least one pocketknife and once you've carried it for a while, you'll understand why.
