Another name for a compass saw is a __________ saw.

The correct answer is "keyhole" saw. A compass saw, characterized by its narrow blade and a handle that allows for intricate cuts, is often referred to as a keyhole saw because of its ability to cut small, detailed shapes and holes in wood. The term "keyhole" specifically emphasizes its use in creating openings for things like locks or peep holes, which require precision and a delicate touch. This style of saw allows the user to maneuver in tight spaces, making it ideal for detailed work, distinguishing it from broader saws like hand or jigsaw saws, which serve different purposes and cutting applications.
