Husqvarna 536LiHD60X

Fully charged, this 36-volt lithium-ion-powered hedge trimmer runs for about an hour and a half, readily shaping a yard's worth of shrubs. The nearly 2-foot-long blade has 60 laser-cut teeth lining both sides to make short work of branches less than an inch in diameter. And the pivoting rear handle makes it easier to shear off the sides or tops of hedges by keeping your hand in a neutral position. [$499; husqvarna.com]
