A jigsaw is an essential tool that can cope with many different jobs and materials due to the wide range of available blades. Buy one that has an electronic variable speed, giving greater control for curved cutting, and an adjustable pendulum cut—useful for ripping down the grain or coarse cutting of plywood. Another feature to look for is a method of clearing sawdust from the cut line, usually by blowing the dust away. Blades can be bought in mixed packs, but it’s best to just the types you need for a particular job, fine-toothed scrolling blades being a top choice. Carbon-steel blades are the best by far. The black plastic plate is a shield that fits over the metal shoe of the saw, preventing any scratching on lumber. The small clear plastic part is an anti-split device: because the jigsaw cuts on the up stroke, it can tear delicate lumbers or plywood when cutting across the grain; this plate, inserted around the blade, minimizes that effect.

The fine teeth of scrolling blades enable the jigsaw to be used for cutting elaborate curves. This model is fitted with a dust extractor adapter.
