A hand saw with a handle (2) and an elongated saw blade (3) connected thereto and having saw teeth along one long side thereof and a back along the opposite other long side has a back ledge (6) arranged on the back and transferable between a first position in which it stiffens the saw blade substantially and a second position of being moved away, in which it is adapted to allow sawing through materials having a thickness exceeding the height of the saw blade. The back ledge is displaceable in the longitudinal direction of the saw blade along the back of the saw blade from said first position and rearwardly at least partially beyond the handle end of the saw blade for obtaining said second position of being moved away, and conversely. |
