I see they extend the concept of "EDC" to things like briefcases. Other than reading material, I have no papers in my briefcase. Just a laptop, some tools, and a few "tools" I'd rather my employer never find out about.
I used to teach survival course for my teams as I was the E&E / SERE NCO for our unit....... I stressed that if it wasn’t in your pocket or you were wearing it you wouldn’t have it when the SHTF .
We used a simple soapdish mini survival kit back then that was dummy corded to the troops pocket. We modified out gear with extra long rigger belts, used 550 para cord as our boot laces. Leatherman or other brand of multi-tools . Layered our clothing . Practiced the fine art of multi-purpose use or don’t carry it if at all possible.
EDC has good and bad ideas yet brings to light some cool why didn’t I think of that deals. Like using a multi-pocket large baby / diaper bag that is durable as heck vs a expensive maxpedition or bag master gear bag......it works well !
one cool item recently added to my emergency gear was a jerven bag that is perfect ! I used a homemade vacuum packing system I have to pack it down to the size of a paperback book. It’s issue to troops in Norway. I tested it during our last cold rain / sleet storm. Stayed toasty and dry.

As to work place PC carry. I use an ankle rig for a snub 357 340S&W w/ 2 spare bianchi speed strips and a small altoids can pressed into service as a personal survival kit. Only other items really carried are a Surefire E2 defender, a fire steel rod on my key ring and a LM tool. Neck lanyard with company ID card has a Photon IIIS on it and my wallet has a few rakes, pick and torsion bars for doors that need to be opened in an emergency. Finesse vs breaker bars per se..... A messenger bag carries my lunch and a couple bottles of water along with a weather shell and a small blow out kit for medical emergencies albeit the ladies bathrooms usually have all the emergency bandages one will need ...
Primary skills and how too ideas should be carried in yer mind vs any tool or gear bag. But simple tools make it easier .......just a few will do .
Stay safe !
