Long time lurker and first time poster here.

My wallet, keys, phone, and Palm aside, I always have my Wenger SAK, an 8 LED flashlight, a Fox 40 Mini whistle, and a lighter. These are in typically in my pockets or in my almost-EDC pack which also contains a bunch of other items. These include meds, spare batteries, spare keys, a cash stash, duct tape, electric tape, and zip ties, among others.

Compared to many others here, I'm still pretty ill-equipped. Right now, I still don't have a first-aid kit I'm satisfied with. I'm slowly building up my kits though.
