pen vs sword

I don't agree! Sword is more sharper, when it comes to the killing effect its pen.

I think it is, "The Pen is mightier than the sword." Pen is never SHARP than sword. You can kill only a couple of men by using a sword. But a leader, who owns a pen can write down in a paper, in just a few words to execute an order of mass killings or war. So that makes the pen mightier than the sword.
