A new screwdriver for special works, characterized in that it consists of handle and rod and the latter is constituted, at its upper end, by a thick-walled tube provided with two fixed sheets placed diametrically on either side of the central hole, which appears another sheet equal to the lateral, but susceptible to take two positions, one of them continuing the straight line of the other two and another, twisting so that it is placed transversely, which is effected by the action of an inner spring that works when the fixed sheets, in contact with the material in which they act, undergo a pressure, the moving sheet being fixed in one or the other of its two positions by virtue of a pivot that is held inside an elbow slot, the position corresponding from the moving blade to the pivot position at one or the other end of said slot.
