Your usual variety of power and non-power screwdrivers will work just fine for most tasks, but might be too large for those micro-sized jobs. In those instances even a super-small manual screwdriver could be awkward to use. The Model 500 Cordless Precision Screwdriver from General Tools could be exactly what you need. This mini-flashlight-sized, battery-powered and ergonomically designed device comes with eight different interchangeable slotted, Phillips and Torx bits and operates in forward and reverse modes. The Model 500 sells for $30 and can be purchased from the manufacturer at www.generaltools.com/500.
