Keyhole Saw (Compass Saw): A Comprehensive Global Industry Guide for 2026

Introduction to the Keyhole Saw (Compass Saw)

The keyhole saw, also known as a compass saw, is a specialized hand tool designed for cutting curves, intricate shapes, and small-diameter holes in various materials such as wood, drywall, plastic, and metal. Its defining feature is a narrow, sharp blade that tapers to a point, allowing it to start cuts without a pre-drilled hole. The handle is typically ergonomic, often made of wood or rubberized plastic, to provide a firm grip during precise cutting. This tool is indispensable for electricians, plumbers, carpenters, and DIY enthusiasts for tasks like cutting out electrical boxes, plumbing openings, and creating custom shapes in sheet materials.
