Woodworking jigsaw

                                                          Jigsaws→     Slower than other handheld power saws, jigsaws are best suited for cutting boards and thin sections of timber. Due to the narrow sizes of the blades used, jigsaws can be used to cut curves as well as to make straight cuts. The blades of basic machines move straight up and down. However, jigsaws with an orbital or pendulum action cut into the work on the upstroke and away from it on the downstroke. This back-and-forth swinging action aids in chip removal.You can adjust the extent of the pendulum action to get the desired result.
