The pen is mightier than the sword because you can take one of those bank pens with the chain on them and attach another pen to the end of them and get pun-chucks out of them.
True you can attach two swords together to make sword-chucks but as 8-Bit Theater taught us, sword-chucks are both hard to wield and take at least 300 pages worth of comics before they show up for common use, hence the superiority of the pen.
I will not be taking any questions at this time.
