Most scissorslike grass shears require a continual squeezing motion, which can eventually cause pain in hands and forearms, or even carpal tunnel syndrome. Now, a new battery-operated model--the Ryobi 12-volt Grass Shears--makes the job quick, easy, and pain-free.

With just the push of a safety button and press of a trigger, the dual blades clip the grass instantly. The clippers are also useful for deadheading flowers on herbaceous perennials such as coreopsis, lavender, and Santa Barbara daisy, but they should never be used to cut tough, woody growth.

Maintaining the shears is simple. After each use, pull out the battery, wipe the blades with a clean cloth, and plug the battery into its 120-volt AC charger for at least eight hours.

Ryobi Grass Shears are available at many home improvement centers; the suggested retail price is $69.99. To find a retailer near you, contact Ryobi at (800) 345-8746.
