This is a good driver set to have on hand for those occasions when you have to deal with small screws, whether to access the battery compartments of small electronics or for impromptu repairs to a pair of glasses.
The wings of the bit holder fold out to create an easy-to-grip handle, and the ratchet mechanism operates right, left or locked. It comes with eight interchangeable bits (#00, #0 and #1 Phillips; 1.5mm, 2mm and 3mm slot; T-6 and T-8 Torx) that are ideal for working with the small screws on toys and many electronics.
The bits, hardened to Rc51-54, are stored in the wings of the handle. At just 2 1/2" long when folded, it won't take up much room in a toolkit or drawer.
