Bokkusu no ken. I just used Google Translate on the words box sword. Bokkusu no ken is what I get.

I know, I didn't put much thought into it, but still it works.

This. It's funny and good for the environment. What's not to love?

I must say that I love you all. Your responses, while not what I expected, have been more than wonderful. :D

I should like to address some names that stood out for me:

Excaliboard: A very nice combination, I was intrigued. However, the differences in size between the two require me to strike it down. Excaliboard is a very elegant name. This weapon is not anywhere near elegance.

Excaliboard and Paper Cuts: This is a project to which I shall devote myself in due time. It's too good to pass up.

Recyclable Rage: A green message to complement the red on the battlefield. This one is closer to the mark.

Bitch Be Cool: I like the attitude this one conveys.

Flatlander: I like this one because it's closer to the more serious tone I was going for. Then again, how seriously can you take a weapon made of cardboard? :P

Ragnabox: Even better. Cardboard shall bring about the end times!

If anyone's interested in backstory (or why I made such a monstrousity), the sword is supposed to be disproportionate to humans because it actually belonged to a giant. This giant was then killed in single combat by a member of the nomadic northern tribes. It is now his primary weapon. This is all for an eventual character I will put together in Pathfinder or something.

Yes, I bring props to game.

Y u mad, bro?

He who kills all!

or

God killing Cardboard!

'cause it looks dumb
 

The Compensator

Excalipoor.

Final Fantasy references ftw, yo.

This is what its name will be.
