why do you need one? I see a lot of "edc" stuff online where people seem to carry knives and tools with them everywhere they go. I've never found a need to do so and never been caught out in a situation where I would have benefitted from a knife.

When I was a kid, my dad told me that all gentlemen should carry a pocket knife. (And presumably gentlewomen, too, but he was addressing me at the time.) I carry a nice Spyderco Para 3 with me at all times when I'm not flying somewhere and use it multiple times a day for random stuff like: trimming a loose thread on my shirt, digging out a splinter, trimming a hangnail before it can snag on something, cutting a length of rope, popping a piece of glass out of my shoe, opening an envelope, cutting tape on a box, slicing an apple or a piece of cheese, and so on ad infinitum. On the very few occasions where I didn't have it, I've reached for my phantom knife and been bummed to realize I didn't have the tool I was counting on. Without exaggeration, I use it every single day.

Note that crazy stuff like self defense absolutely, positively does not enter the equation. I mention that only because some people get weird about it in both directions, both "eek, you carry a weapon around?!", and "ooh, ever get to stab anyone?!" No. My primary self defense mechanism is good running shoes and decent stamina.

"My good reason to carry a knife is that God gave me rather weak teeth and rudimentary claws in an evolutionary trade-off. The hairy-armed person who figured out how to put an edge on a suitable rock made it possible for us to be recognizably human in the first place. I wear a wristwatch whether or not I have an appointment to keep, and I carry a pen and/or pencil because I am a literate person whether or not I have a specific writing task ahead of me, and I carry a knife because I am a human and not an ape."

Having some kind of a sharpish edge is pretty useful in my experience. I just use a keychain multi tool that’s more like a screwdriver than a knife but you can open things you can’t with just your hands. A real pocket knife I only bring when camping or renovating or something like that
