Good blade, well made, small enough that people who don't 'get' pocketknives don't lose their shit when you pull it out to open a box or envelope or cut up an apple.
Everything else in my pockets is pretty mundane, though I do keep my bifold wallet in my hip pocket instead of my back pocket. I find that's a lot more comfortable for sitting or driving for long periods. Supposedly it makes it harder for pickpockets as well?
Mostly I like not having to go looking for a knife when I need one. In most situations there's one around somewhere, but if it's in my pocket, I don't have to interrupt what I'm doing to find it. Context switches and all that.
If I'm going out, wallet, keys, and a rigging knife (folding pocket knife with a marlinespike.)
If I'm going into my company's office, a folding lockpick set (from Multipick) because the key for my filing cabinet was lost before I was hired. It's easy to just rock it open with an L rake, it's just a wafer lock, but it can keep anything mildly sensitive safe from accidental exposure.
I plan for the worst when I step outside the front door. The number of times I’ve needed a light is twice the number of times I’ve needed a knife, but both are immensely useful to have even when going on quick trips.

I also carry my phone, keys, wallet and chapstick.
Likewise, if you've been mugged multiple times, either you're really unlucky, are perceived as an easy target, or visit the more risqué parts of the city ...
Either way, stay safe mate!
