E&V is right. Think of the amount of metal between that point on the shield and the coat on the other side. It forces a lot mor distributed pressure on that "high point" of the designs on both sides.
And if I'm not mistaken, the reverse is actually the hammer portion of the die in the new presses, meaning it is the one in motion more, may get hotter and fail easier.
