Hacksaw

A multi-purpose saw with a narrow blade fixed at each end in a rigid curving frame. Pictured here are typical designs. The lower-left one is designed for more rugged work. The one on the right is generally known as a "jigsaw", and is capable of much finer work, because it can make sharp turns. Blades of various types are available for each. There are also electric motor-powered models with reciprocating blades. A band saw may be an alternative to these.Also see adze, chisel, circular saw, crosscut saw, file, gouge, kerf, miter, rasp, surform, and wood.
