Like all of the controlled "snaps", it works a lot better if you score the 
rod first.  Use an angle grinder to make a notch in the rod, then snap it 
in a vise.

Oh, and by the way ....... WEAR SAFETY GOGGLES !!!!!!!

Once you have done this simply grind near flat, then place the rod in a 
drill press and surface against a grinding stone or wet-and-dry paper.  See:
