Being prepared is key
Quick: what's on your keychain? Well, keys, right? Plus a selection of the following: half a dozen shopper's club cards, your RFID for the gym, a flash drive, a bottle opener, a small screwdriver, an authenticator, and some sort of talisman that shows off your geekdom. Yep. Us, too. You're our kinda people. Some people carry nothing but keys on a ring and others carry every tool known to man. We're somewhere in the middle.
Something else we could see adding to your keychain: an LED flashlight. Shorter than a business card and about the size of a standard Sharpie in diameter, this Screwpop Flashlight 2.0 performs its function without getting in your way. Plus, if you add this flashlight and you have a bottle opener on your keychain presently, you can take it off. The carabiner-style clip on this flashlight functions as a bottle opener, too.
