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:
