A hand-held driving tool kit includes a plurality of hand-held driving tools each having an elongate handle which defines a tool axis and is suitably shaped and dimensioned to be graspable within the hand of the user. The driving tool may be in the form of a fixed, precision or other drivers in which the driver members, such as flat blade and Phillips screwdriver tips are mounted at one axial of the handle. The handle defines a driver axis generally coaxially aligned with the tool axis. At least one of said driving tools of said kit having at least one permanent magnet is provided on the handle, the magnet being formed of a magnetized material having north and south poles defining a magnetic axis generally arranged on the handle to permit selective placement of a magnetizable element at at least one position along the magnetic axis at a predetermined distance from one of the poles to magnetize the element and placement of the element a distance greater than such predetermined distance of the other of the poles to demagnetize the element. The magnetic axis is either aligned with or offset from the driver axis. In this way, a magnetizable element may be magnetized by positioning same adjacent to one of the poles and demagnetized by positioning the magnetizable element adjacent the other of the poles. The magnets used have an energy product equal to at least 7.0x106 gauss-oersteds. Although the magnets may be embedded within the handle, the magnets may be oriented in relation to the surfaces of the handle or a hole within the handle to facilitate placement of the part to be magnetized very closely to the magnetizing pole and somewhat more distantly positioned in relation to the demagnetizing pole. The kit allows each of the driving elements to be magnetized and/or demagnetized with a limited number of permanent magnets mounted on the handle(s) of at least one of the driving tools of the kit.
