Found this unholy relic of the past in the Metropolitan Museum in New York City...
Just goes to show that though Final Fantasy 8 is constantly ridiculed for its use of a certain unorthodox weapon, they didn't come up with the concept...
There's a punching dagger (katar) with guns mounted to the sides of it also. So really, anime weapons really aren't that out there. (Oh and as far as swords go? I saw a four handed sword in a museum at one point, meant to be wielded by two people at once.... o.o)

that and it's just awesome
