Corded jigsaws plug into a wired power source to make straight and curved cuts in lumber, walls, floors, and ceilings. Corded jigsaws have longer run times than cordless tools. They have a flat plate that rests on the workpiece to support the saw. The cutting blade is mounted perpendicular to the plate and has a forward-facing cutting edge that cuts material as the saw is pushed across the workpiece. These portable tools can be brought to the workpiece when it's not possible to use a larger tool. The straight blade is narrow to allow users to cut curves and join corners more accurately than other handheld saws. Jigsaws are used in carpentry, construction, and other trades.
