|Mort the Cleverly Named|
I am intrigued.
A shuriken the size of a greatsword? A greatsword that can be thrown as a shuriken? The best new indie rock band of 2012? Inquiring minds want to know about this "Greatsword Shuriken."
Seriously. Because I'd love to help, but I need a bit more info before I can figure out which way to go with this.
I was imagining something more like the thing in the third panel here:http://www.mangafox.com/manga/mahou_sensei_negima/v33/c302/15.html
Although, that might not be all that fair, because it's closer to the size of 4 large-category bastard swords that have been welded together.
For that I just use a spear with gravity blade on it and make it look like this thing.
