Connecting Rod Splitter

How about 2 pins in a vice: Drill a hole on each side of the jaws, tap a 2" long rod into each hole and then just open the vice until the rods hit the ID of the cap and crank open the vice a little more to seperate. Could make some semi circular wooden shoes on the rods to mate up with the ID of the rod. I'd have to do a lot of rod work to justify getting that tool, but if it makes your life more productive, go for it.
