I don't keep alot of stuff on my person, party because it's too combersome.
I have a bob and car kit so I don't feel I need alot for everyday items as I'm usually not more than 200ft from one or other. I keep swapping out items with me depending on my "needs" or area I'm going to. eg. When not at work I swap my swiss lite for full blown swiss army or multitool, extra battery for razr, I may bring a small/basic fsk, extra tinder and wire saw if i have a coat, or swap my flint with the small lighter (pictured).

Typically I keep at least these items on my person:

1x Razr v3c
1x swiss signature lite (pen, flashlight, scissors)
1x 4gb sandisk usb key
1x timex watch (with mini button compass)

1x pill container (tyl 1, alergy, gravol)
1x inova microlight
1x fresnel lens
1x around square foot of tin foil


1x carabiner
1x Whistle
1x flint and saw blade (striker)

1x large space capsule /w:
  3x Spark-Lite tinder
  50-100ft of fish line
  2x hooks
  2x sinkers
  2x small needles
  2x med needles
  2x purification tablets
  2x safety pins
