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

A rotary tool is a hand-held device used to cut or shape materials such as wood, metal, plastic, etc. It typically has a circular cutting blade that spins at high speeds, driven by an electric motor. Jigsaws are similar in concept but use a reciprocating saw blade instead of a rotating one. Band saws are large machines with a circular saw blade that cuts through material much faster than a jigsaw can.
