Compass saw
A compass saw is a type of saw used for making curved cuts known as compasses, particularly in confined spaces where a larger saw would not fit.〔〔
==Characteristics==
Compass saws have a narrow, tapered blade usually ending in a sharp point, typically with eight to ten teeth per inch,〔 but up to twenty teeth per inch for harder materials and as few as five teeth per inch for softer materials.〔 They have a curved, light "pistol grip" handle, designed for work in confined spaces and overhead.〔
The blade of a compass saw may be fixed or retractable, and are typically interchangeable. Partially retracting the blade can prevent flexing and breaking when cutting harder materials.〔
Compass saws are suitable for cutting softer woods, plastic, drywall, and non-ferrous metals.〔〔 The pointed tip of the blade can be used to penetrate softer materials without the need for a pilot hole.〔
