The device includes a guiding device (g,h) for the lower end of the saw-blade (b) positioned at the lower arm (f) of the U-shape in order to prevent the saw-blade from being bent especially at high speed or when used to cut thick materials. The distance between the upper (c) and the lower arm can be adjusted to the thickness of the material. A saw-blade and injury protection element (g) is integrated in the front of the lower arm.
