What is the main feature of a hacksaw?

A hacksaw is primarily characterized by its use of a thin blade that is held in a frame. This design allows for greater flexibility and precision when cutting through various materials, particularly metal and plastic. The thin blade enables the hacksaw to make intricate cuts and provides a significant advantage when handling tight spaces or detailed work.

The frame of the hacksaw often includes adjustable tensioning mechanisms, which secure the blade in place while allowing the user to replace it easily when needed. This adaptability is crucial, as different cutting tasks may require blades of varying tooth sizes and thicknesses, and the ability to adjust the blade tension ensures optimal cutting performance.

Other aspects of hacksaws, like their suitability for other materials and the presence of adjustable parts, may vary, but the defining feature remains the thin blade affixed within the frame, which sets it apart from other cutting tools.
