A '''hacksaw''' is a fine-toothed [[saw]], originally and mainly made for cutting [[metal]]. The equivalent saw for cutting wood is usually called a [[bow saw]]. 

Most hacksaws are [[hand saw]]s with a C-shaped walking frame that holds a [[blade]] under [[tension (physics)|tension]]. Such hacksaws have a handle, usually a [[pistol grip]], with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes.  A screw or other mechanism is used to put the thin blade under tension.

On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. In normal use, cutting vertically downwards with work held in a bench vise, hacksaw blades are set to be facing forwards.
