A legendary japanese swordsmith who made "holy" swords that wouldn't cut through anything innocent. He used the famous 7-layer crafting style.
Masamune's swords are the opposite of Muramasa, because Muramasa's swords were hungry for blood and often "possessed" their owner.

1. A sword in Final Fantasy wielded by Sephiroth. The sharp cutting part of the blade is 8 linear feet. A very huge sword.

To visualize using a sword like this, pick up a F96T12 fluorescent light bulb, only that the hilt sticks out further where the pin at the end would go. Take the fluorescent tube and whack someone across the back with it (people actually do this on Youtube videos!). Congratulations, your friend just got a slight taste of the masamune's sheer power.

2. When you perform a masamune it's when you do the act with the fluoro tube in #1.

3. They make a masamune that you can buy online, but it is much shorter (58 inches +/- 12 inch) because reality technology hasn't caught up with the technology fictional world of Final Fantasy (schizo tech). Even then, today's masamune is very long for a samurai sword. Not too pleasant to use for harakiri rituals (especially in reality where there's no respawn).
1. Sephiroth's Masamune cut through both edges of the hydrogen-filled gasbag on the airship at once.

2. In 2008 I want to give my friend a masamune and inhale some mercury.

3. Memere bought the masamune from Quickly Vanishing Cash.

Noun:

A once great Japanese comic artists who's earlier works provided tons of entertainment punctuated by excellent artwork, action scenes, great stories and dialogue, and the coolest covers ever conceived.

Unfortunately, Shirow has pretty much used up all his ideas since his debut in the early 80's, so now he spends his time using his amazing art skills to draw the most bizarre hentai (anime pr0n) imaginable. They contain a high amount of glossy naked women with small butts being raped by an electrical tentacle beasts or other big breasted, small butt'd women.
Hey man, Masamune Shirow used to kick ass!

or

Dude, there's fuckin' electrical hentai monsters in this shit! I've been Shirow'd!

or

No! Don't pick up that comic! Shirow drew it!
