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.

Introduction to Chinese Factories

Chinese factories specializing in keyhole saws are predominantly located in the Yangtze River Delta region, particularly in Zhejiang Province (Yongkang, Hangzhou, Ningbo) and Shandong Province. These factories range from small family-owned workshops to large-scale industrial complexes with automated forging lines. For example, Great Wall Precision in Zhejiang operates 15 production lines capable of producing 500,000 saws per month, while Shanghai Tool Works, a state-owned enterprise, has been manufacturing hand tools since 1949 and supplies to government contracts. Many factories also offer private labeling (OEM/ODM) services, allowing international brands to market keyhole saws under their own names.
