## Abstract

A hacksaw includes a beam having two ends receivable in a tube and a handle. The tube and the handle each has an orifice and an aperture formed in one end for engaging with the ends of the beam and for maintaining the beam in a vertical position relative to the tube and the handle. A saw blade includes two ends secured to the other ends of the tube and the handle so as to form the hacksaw. The two ends of the beam are received in the tube and the handle so as to form a compact folded configuration when the saw blade is disengaged from the tube and said handle.
