Then since it would be practically impossible to make the coating PERFECTLY uniform, you would wear through some and still have coating on what's left of the edge-then the hone would wear the edge unevenly.
It really does'nt work on drill bits-other than for non-professional use.The coating wears off,almost immediately . Most very high end drills are made from a steel alloy containing COBALT. It seems they are trying to reinvent the wheel. Most custom razor makers have a very good working knowledge of metallurgy and manipulate the materials molecular structure to make a more durable edge.
There are already very fine steels, some found on even on vintage ebay specials. IMO, its just another marketing ploy to sell a product that really isn't needed.:shrug:
