With its 4.4-amp motor, the Black & Decker 12-Inch Electric String Trimmer ST6500 falls comfortably in the middle of the company's offerings. It is powerful enough to slice through tall weeds and heavy grass, yet lightweight enough (4.8 pounds) to maneuver in and out of tight spaces with ease. The secondary handle slides up and down the shaft, making it convenient to pick a comfortable position. Its 12-inch cutting swath is wide enough to make most trimming chores go by quickly. But the ST6500's coolest feature is its two-in-one capability. To transform it into an edger, you just push a button, spin the Groom 'N' Edge head 180 degrees, flip down the edge guide, and you're ready to cut a manicured edge along sidewalks or driveways. This unit includes a replacement spool and a cord retention system that ensures that it doesn't come unplugged.
