What does a Jigsaw's pendulum action do?

A jigsaw's pendulum action refers to the mechanism that allows the saw blade to move both up and down and in a slight forward and backward motion. This action enhances the cutting efficiency by allowing the blade to cut on both the downward and upward strokes, which can speed up the cutting process and help produce smoother cuts. The pendulum setting can often be adjusted to suit different materials and cutting needs, providing versatility for various tasks.
