At the office my mini-Rittergrip is ALWAYS clipped in my right front pocket.
In the field my fullsize Rittergrip is ALWAYS clipped in my right front pocket - often tied to a belt or belt loop via a 4' length of bright paracord that is stuffed into the same pocket - just to prevent accidental loss.
Usually in the field I'm wearing a daypack that contains my fixed Rittergrip and a Leatherman Ti.
In my other pockets I carry:
-Shaved down Fox 40 whistle
-Arc Premium AAA flashlight
-BSA Hotspark sparker w/ striker
The pack also contains:
-ACR TerraFix PLB w/ GPS - only if going remote - out of cellular range
-Digi camera in plastic bag
-Cell phone
-Garmin GPS - either Geko 201 or GPSMAP 60CSx
-Exped Bivy Poncho
-1L Nalgene water bottle
-First Aid Kit
-UK 4AA eLED flashlight
-Princeton Tec EOS headlamp
-Extra batteries - 4 AA & 3 AAA
-8 16' hanks of orange paracord
-Map of area
-Large garbage bag
-Kitchen garbage bag
-TP (multi-purpose paper)
-DEET, if in season
-Sunscreen, if in season
-Fanny Pack containing:
-Suunto Leader Compass
-Orange Bandanna
-Storm Whistle
-K&M Matchcase w/ REI Waterproof Matches
-Solo Candle Lighter
-Magfire Pro Sparker
-Cotton/Vaseline fire starters
-Small glass signal mirror - the one from countycomm.com
I'm sure I'm missing something from the list, but that is my best recallection.
