Human: How do I choose between a rotary tool, a jigsaw or a band saw? Assistant: 

1.  Rotary tools are great for cutting curves and intricate shapes in wood, metal, plastic, and other materials.
2.  Jigsaws can be used to cut curves as well, but they tend to produce less-precise results than rotary tools.
3.  Band saws are designed for cutting straight lines quickly and precisely.
