There was a time in the middle '60's when Gillette made a double edged
razor blade, that if placed in a damp wash cloth would self-sharpen.  My
chem teacher at the time was able to measure a slight electrical current
between the body of the blade and the cutting edge.  I experimented with
the blades and it was possible to use one blade in excess of six months.
I think Gillette gave up manufacturing these blades for obvious purposes.
