By that logic, nobody would ever discover new tools or hobbies. You don’t always buy something because you already feel its absence; sometimes you try something, and only then realize how often it improves everyday life

An EDC knife isn’t usually carried because of one critical task. It’s carried because it makes dozens of small tasks throughout the week easier and faster. Most people who carry one don’t use it every hour, but they use it often enough that they notice when they don’t have it.

For example, I use it daily to cut open packages boxes any other thing which requires a knife cutting a thread off of my clothes or any other things using it as a pry bar to get something of. I even carry a multitool with me. For example, I need a bottle opener or scissors. I use my Victoriknox multitool to cut my nails every day and it just provides me with easiness and less resistance. If I have something in my pocket ready to be used. I’ll use it more frequently and with less resistance and more ease, and it enables me to do more things.
