Compass Saw
The long narrow blade of a compass saw is used for cutting holes in softer woods or in drywall, such as cutting a hole in a wall for a new electric switch. Compass saws have a wider blade than keyhole saws, for cutting straight lines with little clearance. Most compass saws have a single handle to which various blades can be fitted.
For cutting tight curves, the narrow blade of a keyhole saw is recommended to reduce binding of the blade.

Tool Tips
Apply light pressure while cutting, and make repeated cuts.
Heavy pressure will cause the blade to jam and travel from the desired path.
Prepare Before Use
Tighten the blade firmly to the handle.
Check your worksite with a stud finder, and confirm the absence of electric wiring.
Mark your cut path with a pencil.
Drill a pilot hole into the drywall or material for the blade tip to enter.
