My keychain. It's got 2 flashlights (the Photon and Arc AAA), a Traser Glowring that will glow in the dark for 10 years (it's, um, radioactive), a Swiss Army Rally knife (with a bottle opener, phillips screwdriver, regular screwdriver, nail file, tweezers & toothpick -- oh, and a knife of course), capsule with some cash and Pepsid antacids, a Spyderco Ladybug knife, and a safety pin.
It's all held together by a flat wire gate mini-carabiner.
There's also an NYC subway token, which you can't really see.
Incidentally, I edited the cuts on the house key, so don't go trying to dupe it from the picture. Actually, it's practically a bump key in this photo.
