I'm a little confused about the difference between a rotary tool, a jigsaw and a band saw.

Rotary tools are used to cut curves and arcs in wood. They typically have a circular blade that spins at high speeds. Jigsaws are similar but instead of having a single blade they have two or more blades that move in an orbital motion around each other. Band saws are used to cut straight lines across long pieces of material. The blade is mounted on a frame that moves back and forth along a table.
