Power metal shears. Looks like a drill but has 3 finger-nose that cuts the metal. The middle finger moves up and down to cut while the other two outside fingers are there for a shearing surface. You lose a bit of material (3/16") but the stock on both sides comes out flat. There are hand shear versions like that as well that I haven't seen in a while, but that is the way to make flat cuts.
