This interchangeable-tip small screwdriver has a unique internal bit clip that could have been designed for a science-fiction film. Just press a button, and the clip slides slowly out of the handle as if actuated by a hydraulic cylinder, taking about 5 seconds to deploy fully.
Despite its mesmerizing action, it is a well-conceived and useful tool for working with the small screws commonly found on assembled consumer products. The 20-tooth ratchet mechanism is reversible, or can be fixed. Supplied with eleven interchangeable bits (#00, #0, and #1 Phillips; 2.0mm, 2.5mm, and 3mm slot; and T-6 to T-10 Torx).
A tip cap lets you slide it safely into a pocket without removing the bit. Measures 6-1/4" long overall. As intriguing as it is practical.
