What have you stopped or never did every day carry that some people do?
Esp. interested in what you thought you might need but never used.

More than 1 knife.

Cell phone belt pouch/holster/clip - kept catching on things.

The latest and greatest portable tech - I know it costs $50, but it does what I need it to, and I get to keep the additional $400 in my pocket.

Gel pens - Leak a lot, and difficult/impossible to wash out. Capped ballpoints almost exclusively for EDC.

Food. I replaced what was in my pockets with what is around my middle.

A multi-tool or Swiss Army knife. I just EDC a folding knife now, and take my box of tools along if I will be doing something requiring that.

Gum - stopped eating sugar, and don't like artificial sweeteners
chapstick - not worth the carry for infrequent chapped lips

I carry an emergency stash of $$. Haven't had to use it yet, but just one time will be worth it....

I stopped carrying most things.

I used to have a small FAK. I used the bandaids a few times but that was about it so that has been removed.
Most of my wallet. I really only carry two credit cards and my driver's license now. I keep some cash at home and in my car in case I need it. All those other cards that companies want me to keep sit in my glovebox.
I still carry a small notebook, pens and cellphone, but everything else has been pared down.

I never carried as much as some people, but I stripped everything down to just what I actually USE every single day. Wallet, cellphone, folding knife, flashlight, wristwatch (OK - in truth, some days the phone never rings, and many days I never touch the wallet). I also carry two things I don't use every day, but would never leave home without, and hope to never need to use - a firearm and spare magazine. That's it. I am very minimalist now. Everything else I carry in a bail out bag that may or may not go in the car with me, depending on where I'm heading and what I'm planning on doing. Lots of stuff in that bail out bag for sure, but it doesn't ride in pants pockets anymore, so not what you'd term EDC. It's typically close at hand, but not physically on me any more.

I used to carry three extra magazines, then two, and now most days it's one.

Wristwatches started aggravating my tendonitis, my phone started having a clock on it, so I stopped wearing one most of the time, excepting my GPS watch when running.

I traded glasses for contact lenses -- they work better for me. But sunglasses became a must.
