that is wrong on so many levels but
I don't like changing from default names, so I tend to call her Dagger. But, like Raian, I have changed it to Garnet on occasion. I did once change it to BrdSword (or something similar, I can't recall what the character limit forced me to change it to) during one play through, due to her little chat with Zidane about what each blade was called.
I would have trouble naming her BrdSwrd. Every time I look at it I would think "Bird Sword" and that's just horrible. I mean, a sword made of birds would look cool, but it would be very cruel. Especially if it were a fire sword. I don't think I would enjoy hitting people with a sword made of flaming birds. Well, I would, but I wouldn't want the birds to be hurt. Although they'd be in constant pain because of the fire anyway. What was I talking about?

I always used Dagger. Her wit was as sharp as the edge of the blade (lawl, poetic nonsense failure), and it connected her with Zidane. (I could imagine Steiner silently pissed over his princess choosing a name connecting her to the thief who kidnapped her.)
More "I can't wait to execute you" pissed.
