Chainsaws have come a long way since the days when Leatherface first terrified buxom scream queens. With this 6400 rpm electric model, we cut three dead trees into four neat piles of firewood before running down the first battery. A hefty yet nimble 12 pounds, the PowerNow CS250E ($499) had plenty of torque to pull through branches, a particle board couch (see inset), tree trunks and a mannequin head we found curbside. And at a peak of 86 decibels, it’s about 30 decibels quieter than gas-powered options. With that kind of stealth mode, it’s probably best kept out of the hands of Texas Chainsaw Massacre-ers. Assuming you’re not one, check it out here.
