Sorry for resurrecting this, but here's a pic of my minimalistic EDC keychain:
- VARGO titanium whistle
- house key with a True Utility Keytool
- tiny capsule with a piece of waterproof tinder and two spare flints in it
- Victorinox Classic
- Photon Freedom Micro with the neck lanyard thingy as a button protection
- County Comm Brass Wheel Sparker taped to the thingy with the actual lanyard of the Photon wrapped around.
