The right power saw can save you a lot of time and effort. A circular saw is great for jobs where you’re cutting straight, precise lines. For more detailed cutting, such as curved corners and profiles, choose a jigsaw. Tougher jobs such as removals, demolitions and cutting hardy materials will need a reciprocating saw. Corded saws pack more power and are great for larger tasks; while cordless saws let you tackle the job easily without wires and extension cables.
