Although my loads get lighter during these Alabama summers it is not unusual for me to roll into work packing 2 multi-tools, 2 knives, and 2 flashlights with the intent to test out 1 of each. I try to stay in the 2/2/2 range because it's nice to have a back-up of my essential items.
Here's what I've carried for at least a week this past month.
Nothing too crazy but once winter rolls around all the above goes away and I get into the extremes with 4 knives, 1 gun+1 mag, 3-4 full-size flashlights, 2-3 multi-tools, lighters, etc. I need something to fill the big coat I wear.
Unless they are Police or military, why would you pack so much junk around every day?
Testing and evaluation of certain items that I plan to use long-term but don't want to carry by themselves in case they do not meet my needs. Also, I tend to spend a lot of time around other people and like to be prepared with a lent light/tool for them. That, and it's just really fun to walk around like Inspector Gadget sometimes.
So, what do you real people carry everyday?
Non-internet knife/tool/light/EDC hobbyists seem to carry pretty similar items. Over the past few years I have been observing what people EDC and it seems like the most common "geardo" items are:
+Vic classic or knockoff
+Photon or other small keychain LED knockoff
+Folding utility knife
Seems like a step down at each level of tools; few carry a hand-held flashlight, more carry a multi-tool, and most carry at least a folding knife of some kind.
