My normal work day EDC :
These  are always on my person :  
 # 1  belt pouch (about the same size a Maxpedition M1 pouch) with  a white Photon 3 and a red Freedom microlights.
The pouch contains, inside the small outer pocket, some band-aids, etc.. and in the other compartments the following items :
# 3  different sets of ? papers ? (ID, driving licence, credit cards, a.s. o. 
# 6 spare batteries for 6P and Photons, sewing kit and small Bic lighter
# 7  large garbage bag  + (on top) fresnel lens
# 8  gentleman folder
# 9  small pen
# 10  flat whistle + lanyard
# 11 money purse
(not shown) car + house keys
In pant back pocket
# 2  Doug?s RSK, 
On my belt 
# 4   Surefire  6P 
# 5   Leatherman PST 
# 12 cell phone
When traveling by car or train, I add a Fred Perrin's "griffe" around my neck.
Never far away :
during normal workdays, I  carry a Maxpedition Condor backpack, with papers, portable computer, small set of tools, cables, CDs  etc...
+ large garbage bag + Doug's PSK + emergency poncho + small FM radio + Inova 24/7
Sometimes, when an office's party/lunch is planned, I take a nice looking folder along (a custom "Thiers" knife).
That should do it !  
( I guess I don't need to mention shoes, pant, shirt, underwear a.s.o.   ....  <img src="/images/graemlins/grin.gif" alt="" />)
