The Stanley FatMax Wallboard Jab Saw features one of the most advanced tooth designs in our product line. Our tests show that Stanley's proprietary SharpTooth technology can cut on push and pull strokes-which means significantly less effort for the user. This approach is 50% more efficient than traditional tooth designs. And our new, extra sharpened tip jab saw has been expressly designed to punch effortlessly through the toughest wallboard, wood, and plastic materials. What's more, the unique handle design makes this impressive new tool more ergonomic than ever before, with a slip-resistant grip for greater comfort, even during extended use.
