ABSTRACT:
A method and apparatus for extending the life of blade cutting edges comprising a unit having at least two oppositely charged permanent magnet polar surfaces which pass strong magnetic lines of force directly into the blade cutting edge from close proximity opposite polarity magnet polar surfaces aligned in a polarized configuration unit so that the coinciding lines of force pass through the cutting edge and turn into the blade.
