ABSTRACT:
An improved blade tensioning mechanism carried by a hacksaw handle is disclosed. It consists of a longitudinally extending frame member with a handle attached at one end and a pivoting lever attached at the end opposite the handle. A blade anchoring pin, or pins, are located on the pivoting lever and on the handle allowing the attachment of a blade. The pivoting lever has attached to it an extension bar that substantially runs the length of the longitudinal frame member and, when turned in a clockwise direction, is captured at the handle end with a spring loaded lock located at the top of the handle portion of the frame. Fine adjustments to the amount of tension are accomplished by the adjustment of a screw which effectively lengthens the longitudinal member with relation to the blade anchoring pins, raising or lowering the amount of tension accordingly. The screw is tightened with the tension released from the blade. A cushion safety grip provides protection against accidental dislodging of the spring loaded lock.
