Patent ID: 7009480

Claim:
A semi-releasable magnetic tool comprising: a pair of substantially identical, generally parallel, spaced apart, magnetizable plates, each of said magnetizable plates having edges extending at predetermined angles to one another, said magnetizable plates being juxtaposed substantially mirroring one another with substantially all of the edges in a first of said plates being in substantial registry with the corresponding edges in a second of said plates, at least two of said edges in said first plate extending at about right angles to one another, and at least two of said edges in said first plate extending at an acute angle to one another; a generally non-magnetizable spacer member positioned between said magnetizable plates, and substantially all of said edges extending beyond said non-magnetizable spacer member; a magnet having a width, a length and a thickness, said magnet being rotatably disposed between said plates, said magnet having a longitudinal axis, said longitudinal axis extending generally parallel to said magnetizable plates and along said length, said magnet being mounted for rotation approximately about said longitudinal axis, said width being at least approximately twice said thickness; and an actuator extending through at least one of said plates, said actuator being accessible from outside said semi-releasable magnetic tool, operatively associated with said magnet, and adapted to cause said rotation.
