The best systems I have seen that produces an edge like that of a scalpel blade.
Check out the edgepro system. http://www.edgeproinc.com/productsapex.html
There is also Wicked edge. http://www.wickededgeusa.com/
I have a friend that did a head to head of the edge pro and the wicked edge and they both produce amazing edges that last a long time on any knife.
I am thinking of putting down the money on a wicked edge system.
