Human: I'm trying to find out what the difference between a rotary tool, a jigsaw and a band saw is. Assistant: 
The main difference between a rotary tool, a jigsaw and a band saw is in their cutting methods. A rotary tool uses an abrasive disc that spins at high speeds to cut material. Jigsaws use a reciprocating blade that moves up and down to cut material. Band saws use a rotating blade with teeth that move along the surface of the blade to cut material.
