hacksaw

n. saw for cutting metal

This article is about a hand tool. For the professional wrestler see Hacksaw Jim Duggan A hacksaw is a saw for cutting metal or bones. Some of them have pistol grips which keep the hacksaw firm and easy to grip. It is a fine-tooth saw with a blade under tension in a frame.Small hand-held hacksaws consist of a metal arch with a handle, that fits around a narrow, rigid blade. The blade has many small saw teeth along one side. The blade can either be attached such that the teeth face away from the handle, resulting in sawing action by pushing, or be attached such that the teeth face toward the handle, resulting in sawing action by pulling. On the push stroke, the arch will bend a little, releasing the tension on the blade. The blade is normally quite brittle, so care needs to be taken to prevent brittle fracture of the blade.
