A holding device includes a lever arm, a magnetic fulcrum and a frictional member which is held against a magnetizable surface with the frictional member normally in contact with the surface. Pivoting the lever arm about the fulcrum raises the frictional member out of contact with the surface so that objects can be securely placed under the lever arm. Releasing the free end of the lever arm causes the holding end to return to the magnetizable surface, securely holding any objects placed therebetween against the magnetizable surface.
