A hacksaw has an adjustable frame with an elongated rear frame member having an inverted U-shaped cross section and providing a downwardly opening channel. The rear frame rearward end portion is secured in the upper portion of the hand grip and its side walls adjacent the forward end have lower portions which extend inwardly and incline upwardly towards the forward end to provide an upwardly inclined ramp. This ramp substantially closes the channel and terminates in a lip at the forward end of the frame member, and the top wall and side walls adjacent thereto are relieved above the ramp. A front frame member of bar-like configuration having a bridge portion seated in the channel of the rear frame section, and a depending leg portion at its forward end which has a blade mounting element adjacent its lower end. The bridge portion has spaced recesses in its bottom edge in which the lip of the ramp is seated. The frame also has a rear leg member extending below the rear frame section forwardly of the hand grip, and its upper end portion is seated in the upper end of the hand grip. This leg member has blade mounting element adjacent its lower end cooperating with that of the front frame member to secure a blade extending therebetween. The length of the frame is adjustable by pivoting upwardly the front end of the front frame member to disengage the ramp from the recess of the bridge portion, and the bridge portion is slid within the channel of the rear frame member to align a desired recess therein with the ramp.
