BLACK & DECKER introduced the Gyro 4-volt Max, the first motion-activated screwdriver that controls variable speed and direction.

With the tool’s gyroscopic technology, users rotate their wrist one-quarter turn to the right for forward or left for reverse, rather than by engaging a trigger. It will sell at most major retailers for $39.97. For information, visit www.blackanddecker.com.
