You need this. Anybody who's ever made a third trip to the hardware store on the same day needs this. The (100) -- count 'em, (100) -- chrome vanadium driver and bit attachments include slotted, Phillips, square (Robertson) head, torx, hex and 12-point bits, plus security Phillips, torx and hex, and (4) different driver adapters (one of which, a super-cute cup-hook driver, has us oddly excited). They're all in a flip-top plastic case. How come it's surplus? If you turn it upside down and shake it, some of the bits fall out of their little size-marked slots. So don't do that. Or stick a thin sheet of foam inside it and all will be well.

They measure 3-1/2" long x 9/16" dia and hold 5ml, are graduated in .2ml increments, and have threaded tops. Note the throwaway price.

Saves you from info-snatching electronic pickpockets, and from leaning against the gas pump and emptying your bank account. (The downside of Radio Frequency IDentification.) Called the "EMvelope," it's an 8-3/8" x 3-1/2" x .012" thick trim-able electromagnetic sheet (think Faraday cage with a floating ground) that blocks radio frequencies up to 2.4GHz. Cut it to size and slip it in your wallet, or wherever, and protect the data on your credit cards, "fast-pay" devices, ID cards, EZ-Pass, or anything else with an embedded RFID chip, including the new U.S. passports.
