It's a
SwissTech multitool (the 8-in-1 variety). 2 sizes of each screwdriver, which I rarely use, but the pliers/wirecutters are amazingly handy (I don't wear a belt barely ever, or I'd have my Leatherman on my side), and surpisingly durable (I can't even bend the handle rivets squeezing as hard as I can). Great little package, small and light (I keep a minimum of junk on my keychain, any more than what I have now drives me crazy). I got mine at Brookstone (place w/ massaging chairs

), but they're available in many places if you don't want to go online.
Have yet to find anything better to put on there.
