Never leave home without it!
The "5 C's" of an Urban Ready Keychain are:
2. Combustion - a Bic lighter (in sheath)
3. Cord - 10" long paracord. The "chain" should be knotted in such a way as to be quickly deployed if needed for emergencies.
4. Call Attention - For signalling, a metal whistle and small coin-battery flashlight near carabiner attachment.
5. Convenient Carry - All packaged small and compact enough to be brought along always, attached to your pants or inside your EDC bag.
