"  LoggerHead Tools, best-known for its Bionic Wrench, seems to specialize in tools that are equal parts ingenious and impossible to describe. But it&amp;#039;s worth rambling about the Bit Dr., a weird little multi-bit compact screwdriver that might just change the way you, um, drive screws. It&amp;#039;s small (4 in. closed) and light (6 ounces), with 10 double-sided bits stored in the handle. And the shaft folds out to one of five different positions, ranging from a right-angle pistol grip to a straight, traditional stick-handle.  But it&amp;#039;s the Bit Dr.&amp;#039;s quasi-ratcheting shaft that&amp;#039;s so subversive: When you press it against a fastener, the shaft locks in place, letting you turn the handle and the fastener with it. Release the pressure, and the shaft rotates, for a slightly clumsy ratcheting action. The press release mentions something about turning the shaft with your thumb and index finger, which obviously would give you zero power, and which I completely disregarded. When I finally had to use the Bit Dr. to unscrew something, I got it. The shaft locks, letting you loosen screws with a single twist of the handle. Then, without hitting any buttons, you start spinning the shaft with two fingers, and the screw pops out faster than you can say, &amp;quot;And this thing costs how much?&amp;quot; Which is a good question, because this contraption is $25\u2014a good deal for 21 bits, and one brilliant sequel to the screwdriver. \u2014Erik Sofge "^^<http://www.w3.org/2001/XMLSchema#string>
