A hand tool with a knife, saw, screwdriver blade or the like in which a handle is formed of two U-shaped members of equal length that are pivotally articulated on a blade-retaining piece at free ends of their respective arms about pivot shafts that are perpendicular to each other. The U-shaped members are swingable in succession over a blade as a protective housing that encloses it. The blade is removably fixed by a screw in a receiving slot of the blade retaining piece. The two shafts are mutually offset or staggered in a longitudinal direction of the blade approximately by a thickness of a base portion of the U-shaped member.
