Which saw is designed for cutting curves into wood?

The coping saw is specifically designed for making intricate cuts and curves in wood. Its thin, flexible blade allows the user to navigate tight curves and turns with precision, making it ideal for detailed woodwork, such as creating joints in woodworking projects or cutting out shapes. The blade is typically held in a U-shaped frame, which provides excellent control for making curved cuts. This tool is favored by carpenters and woodworkers who need to achieve accuracy in their cuts, particularly when following patterns or designs.

Fret saws are also capable of cutting curves but are more specialized for delicate work and finer details, often used in fretwork. Carpenter's handsaws are meant for straight cuts and general sawing tasks, while hacksaws are primarily used for cutting metal. These other tools do not offer the same capability for navigating curves as the coping saw does, making it the correct choice for this question.
