I recently purchased a 2Hp variable-speed KMG and I've been experimenting with all sorts of grinding techniques. The first blade to come off of the machine is a little fixed-blade razor, similar to a Japanese kamisori. The grind is asymmetrical with a 10" hollow on the back and 3" hollow on the front.
It's far from perfect, but it shaves smoothly and looks pretty good. The M4 hones like diamond-studded concrete. There was a time that I thought my stones weren't cutting at all.
