Potentially my Mighty Wallet - https://mightywallet.shop/collections/classic-mighty-wallet/...

The rulers on the edge have come in handy the most.

[stadeschuldt]

Also, in case you need the law of cosines in your pocket. ;)

Pocket knife. Clip one in your pocket for a week and you will be amazed how much you use it. I always have a cheap Gerber or nice Kershaw on me.

[leokennis]

Yep. Depending on if I’m going into the office or staying home, I have two Victorinox pocket knives of which I always carry one. Slicing apples, cleaning dirty nails, (un)screwing stuff, prying out a battery, cutting open packages, uncapping a bottle. All from a package-of-gum sized aluminium tool in my pocket

[enonevets]

This. One that doubles as a bottle opener. Something like this: https://www.amazon.com/seller-TAC-Assisted-POLICE-Tactical/d...

My planner. My whole life is there.
