A folding hacksaw having the back (12) of the saw and the saw handle (10) pivotally joined together and pivotally connected to a four-bar linkage comprising the blade (22), side frames (18, 20) and a back frame (32). The back frame is enclosed within the back of the saw. Movement of the handle relative to the back of the saw causes the saw blade to extend from the back or retract into the back in the manner of a folding knife. The movement of the handle places the handle in the proper cutting position when the blade is extended. A top latch (28) maintains the handle in line with the back in the retracted position. A blade latch (30) maintains the saw blade and the handle rigidly in the blade extended position.
