ABSTRACT:
A blade tensioning device for a hacksaw or the like. A generally conventional hacksaw is provided with a plate in one leg of the frame, and the blade receiving pin is on the plate. A toggle joint is arranged to rotate the plate to move the pin and loosen the saw blade or to rotate the plate to move the pin and tension the blade. When the blade is tensioned, the toggle joint locks to hold the blade in tension. The frame has a bezel to fit over the end of the blade when the blade is in tension to prevent lateral movement of the blade. The opposite frame member may include an adjustable link to adjust for saw blade length or slight frame bending.
