If I'm working I carry very little, building security and all. Keys in left front, cell in right front and FAK in my backpack that I use to carry my work papers and laptop. I have a couple of things on my keychain, including SAK Classic and Arc-AAA.
If I'm not working it used to be keys in left front, cell in right front, Leek clipped to right front. If wearing cargos (usually) add a Fenix in left cargo pocket and an Opinel in right cargo pocket. Depending on where I was going I might omit the Leek.
Lately I've been clumsier or something, I decided it would be a good idea to carry a small FAK (really only for boo-boos) even without my backpack.
So now its keys left front, cell right front, Leek clipped to right front and pocket organizer in left thigh pocket, which contains a Fenix, Opinel, pen and paper as well as my homebrew FAK. If I want to carry a fixed blade it goes in the right front and the cell moves to the right thigh pocket. The Leek often gets left home, particularly if I have a sheathed SR Vex in that same pocket.
