Abstract
An apparatus and method for sharpening razor blades and the like whereby rectangularly-shaped magnets are placed end-to-end in a rectangular enclosure that snaps on securely over a razor blade during non-use times in such a manner that the magnetic field generated by the magnets acts upon the cutting edge of the blade so as to maintain the sharpness of the cutting edge.
Claims17
A transportable magnetic blade-sharpening device comprising:
- a. a rectangularly shaped casing uniformly cast from nonferrous material;
- b. two or more elongated rectangularly shaped magnets forming longitudinal axes and each magnet having two opposite planar polar end surfaces perpendicular to the longitudinal axes, said magnets being aligned in an a polar end-to-polar end, like-poles-facing one another-and-touching disposition within said casing;
- and
- c. a means for firmly attaching and securing said casing to a head of a hand-held shaving device when said hand-held shaving device is not in use.

A method for extending a cutting edge's life comprising steps of:
- a. placing two or more elongated rectangularly-shaped permanent magnets in a suitable casing, said magnets forming longitudinal axes and each magnetic having two opposite planar polar end surfaces perpendicular to the longitudinal axes, wherein said magnets being disposed in a polar end-to-polar end alignment so that magnetic charges on any two of said planar polar end surfaces of any two of said magnets adjoining and facing each other are identical;
- b. providing a cutting edge;
- and
- c. attaching said cutting edge to said casing in such a manner that said cutting edge is parallel to and above said magnets.
